Add support for deconstructing by functor number rather than name,
for use by write_binary.

runtime/mercury_deconstruct.c:
runtime/mercury_ml_expand_body.h:
runtime/mercury_ml_deconstruct_body.h:
	Add predicates deconstruct.functor_number and
	deconstruct.deconstruct.du, which returns a functor number
	suitable for use by construct.construct rather than a functor
	name.

tests/valid/agc_unbound_typevars2.m:
	Add a function get_functor_lex, which returns the lexicographic
	functor number given an ordinal functor number.

	Add equivalence types to make it clearer which ordering is
	being used by which functor numbers.

	Remove a C-ism: num_functors now fails rather than returning -1
	for types without functors.

NEWS:
	Document the new predicates and functions.

459847a064 Move the univ, maybe, pair and unit types from std_util into their own
Estimated hours taken: 18
Branches: main

Move the univ, maybe, pair and unit types from std_util into their own
modules.  std_util still contains the general purpose higher-order programming
constructs.

library/std_util.m:
	Move univ, maybe, pair and unit (plus any other related types
	and procedures) into their own modules.

library/maybe.m:
	New module.  This contains the maybe and maybe_error types and
	the associated procedures.

library/pair.m:
	New module.  This contains the pair type and associated procedures.

library/unit.m:
	New module. This contains the types unit/0 and unit/1.

library/univ.m:
	New module. This contains the univ type and associated procedures.

library/library.m:
	Add the new modules.

library/private_builtin.m:
	Update the declaration of the type_ctor_info struct for univ.

runtime/mercury.h:
	Update the declaration for the type_ctor_info struct for univ.

runtime/mercury_mcpp.h:
runtime/mercury_hlc_types.h:
	Update the definition of MR_Univ.

runtime/mercury_init.h:
	Fix a comment: ML_type_name is now exported from type_desc.m.

compiler/mlds_to_il.m:
	Update the the name of the module that defines univs (which are
	handled specially by the il code generator.)

library/*.m:
compiler/*.m:
browser/*.m:

deep_profiler/*.m:
	Conform to the above changes.  Import the new modules where they
	are needed; don't import std_util where it isn't needed.

	Fix formatting in lots of modules.  Delete duplicate module
	imports.

tests/*:
	Update the test suite to confrom to the above changes.

941be20e27 Type_desc__get_functor looks up the types of the arguments of a function
Estimated hours taken: 16
Branches: main

Type_desc__get_functor looks up the types of the arguments of a function
symbol. This predicate used to abort when an argument has an existential
type. This diff makes type_desc__get_functor work even in that case.
However, since in such cases the type of an argument is not a ground type,
this diff has to add the concept of a pseudo_type_desc, a descriptor for
a not necessarily ground type. Pseudo_type_descs are implemented as
MR_PseudoTypeInfos.

runtime/mercury_type_info.[ch]:
	Add new macros to operate on pseudo_type_infos. Most have a structure
	modelled on corresponding macros operating on type_infos.

	Provide versions of MR_get_arg_type_info, MR_compare_type_info,
	MR_unify_type_info, MR_collapse_equivalences,
	MR_type_params_vector_to_list, MR_create_type_info and
	MR_create_type_info_maybe_existq that work on pseudo_type_infos,
	not type_infos.

	Change MR_pseudo_type_info_vector_to_type_info_list, which implements
	the core of get_functor, to return pseudo_type_infos instead of
	type_infos, and rename it to reflect this fact.

	Change to four-space indentation to reduce the number of lines
	that have to be wrapped.

runtime/mercury_make_type_info_body.h:
	Generalize the code for creating type_infos to also be handle
	pseudo_type_infos.

	Change to four-space indentation to reduce the number of lines
	that have to be wrapped.

runtime/mercury_type_desc.[ch]:
	Provide versions of MR_make_type_ctor_desc and MR_type_ctor_and_args
	that work on pseudo_type_infos, not type_infos.

	Change to four-space indentation to reduce the number of lines
	that have to be wrapped.

runtime/mercury_builtin_types.[ch]:
runtime/mercury_builtin_types_proc_layouts.h:
runtime/mercury_hlc_types.h:
runtime/mercury_unify_compare_body.h:
	Add the C types, global variables and functions necessary for the
	new builtin Mercury type pseudo_type_desc. This type must be builtin,
	because its structure (MR_PseudoTypeInfo) is defined in C, and as such
	cannot be unified, compared, deconstructed etc without hand-written
	C code.

runtime/mercury_deep_copy.c:
runtime/mercury_deep_copy_body.h:
	Handle the copying of pseudo_type_infos/pseudo_type_descs. This code
	is almost the same as the code to copy type_infos, but must of course
	handle type variables, and the arguments are themselves copied as
	pseudo_type_infos, not type_infos.

runtime/mercury_types.h:
	Since deep copy needs to create pseudo_type_infos, provide a version
	of the MR_PseudoTypeInfo type without const.

runtime/mercury_construct.c:
runtime/mercury_deconstruct.c:
	Handle pseudo_type_descs just as we handle type_descs: neither can be
	constructed, nor do they have function symbols with named arguments.

runtime/mercury_ml_expand_body.c:
	Provide code to deconstruct pseudo_type_descs. This code is almost
	the same as the code to deconstruct type_descs, but must of course
	handle type variables, and the arguments are themselves
	pseudo_type_descs, not type_descs.

runtime/mercury_tabling.c:
	Catch attempts to table pseudo_type_infos.

runtime/mercury_tags.h:
	Add macros for constructing lists of
	pseudo_type_infos/pseudo_type_descs.

runtime/mercury_wrapper.[ch]:
	Define global variables holding the addresses of the typeinfos for
	describing pseudo_type_descs and lists of pseudo_type_descs.

runtime/mercury_init.c:
	Add the extern declarations required by new code in mkinit.c.

util/mkinit.c:
	Make the addresses of the typeinfos for describing pseudo_type_descs
	and lists of pseudo_type_descs, defined in the library, known to the
	runtime.

library/type_desc.m:
	Add a new builtin type, pseudo_type_desc, for describing possibly
	nonground types.

	Add utility predicates for operating on pseudo_type_descs.

library/private_builtin.m:
	Handle the new builtin type.

	Add builtin typeinfos for describing pseudo_type_descs and lists of
	pseudo_type_descs, since some functions in the runtime need them
	for memory profiling.

library/rtti_implementation.m:
	Handle the new builtin type, mostly by ignoring it, since the backends
	that use this module do not have any notion of pseudo_type_infos.

	Bring the module up to date with our formatting guidelines.

library/construct.m:
	Make get_functor return a list of pseudo_type_descs instead of
	type_descs.

	Change the name of the version of get_functor that returns argument
	names, to distinguish it from the base version by more than just the
	arity.

	Make the order of predicates more logical.

library/std_util.m:
	Change the name of the version of get_functor that returns argument
	names, to distinguish it from the base version by more than just the
	arity.

	However, this name change is effectively the only change: both
	get_functor and get_functor_with_names still return lists of
	type_descs. This means that they will throw exceptions in the presence
	of existential types, but code using them need no algorithmic changes.

library/term.m:
library/term_to_xml.m:
	Add module qualifiers as necessary; no algorithmic changes.

library/list.m:
	Add two general-purpose predicates, all_true and all_false,
	for use in the other library modules.

compiler/ml_util.m:
compiler/mlds_to_gcc.m:
compiler/rtti.m:
compiler/type_ctor_info.m:
	Make sure we handle the new builtin type as a builtin type, and not
	try to have the compiler create a type_ctor_info for it.

deep_profiler/canonical.m:
	Delete the local definition of all_true.

tests/hard_coded/construct_test.{m,exp}:
	Update this test case to test the ability to retrieve the names of the
	fields of function symbols with existential types.

	Add module qualifications as necessary.

tests/hard_coded/construct_test_exist.{m,exp}:
	Add a tougher test case to print the types of the arguments of
	function symbols with existential types.

tests/hard_coded/Mmakefile:
	Add the new test case, and sort the names of the tests.
