    Make these tests use four-space indentation, and ensure that
    each module is imported on its own line. (I intend to use the latter
    to figure out which subdirectories' tests can be executed in parallel.)

    These changes usually move code to different lines. For the debugger tests,
    specify the new line numbers in .inp files and expect them in .exp files.

257efbd678 Store double-precision `float' constructor arguments in unboxed form,
Branches: main

Store double-precision `float' constructor arguments in unboxed form,
in high-level C grades on 32-bit platforms, i.e. `float' (and equivalent)
arguments may occupy two machine words.

As the C code generated by the MLDS back-end makes use of MR_Float variables
and parameters, float (un)boxing may be reduced substantially in many programs.

compiler/prog_data.m:
	Add `double_word' as a new option for constructor argument widths,
	only used for float arguments as yet.

compiler/make_hlds_passes.m:
	Set constructor arguments to have `double_word' width if required,
	and possible.

compiler/type_util.m:
	Add helper predicate.

compiler/builtin_ops.m:
compiler/c_util.m:
compiler/llds.m:
	Add two new binary operators used by the MLDS back-end.

compiler/arg_pack.m:
	Handle `double_word' arguments.

compiler/ml_code_util.m:
	Deciding whether or not a float constructor argument requires boxing
	now depends on the width of the field.

compiler/ml_global_data.m:
	When a float constant appears as an initialiser of a generic array
	element, it is now always unboxed, irrespective of --unboxed-float.

compiler/ml_type_gen.m:
	Take double-word arguments into account when generating structure
	fields.

compiler/ml_unify_gen.m:
	Handle double-word float constructor arguments in (de)constructions.
	In some cases we break a float argument into its two words, so
	generating two assignments statements or two separate rvals.

	Take double-word arguments into account when calculating field offsets.

compiler/mlds_to_c.m:
	The new binary operators require no changes here.

	As a special case, write `MR_float_from_dword_ptr(&X)' instead of
	`MR_float_from_dword(X, Y)' when X, Y are consecutive words within a
	field. The definition of `MR_float_from_dword_ptr' is more
	straightforward, and gcc produces better code than if we use the more
	general `MR_float_from_dword'.

compiler/rtti_out.m:
	For double-word arguments, generate MR_DuArgLocn structures with
	MR_arg_bits set to -1.

compiler/rtti_to_mlds.m:
	Handle double-word arguments in field offset calculation.

compiler/unify_gen.m:
	Partially handle double_word arguments in LLDS back-end.

compiler/handle_options.m:
	Set --unboxed-float when targetting Java, C# and Erlang.

compiler/structure_reuse.direct.choose_reuse.m:
	Rename a predicate.

compiler/bytecode.m:
compiler/equiv_type.m:
compiler/equiv_type_hlds.m:
compiler/llds_to_x86_64.m:
compiler/mlds_to_gcc.m:
compiler/mlds_to_il.m:
compiler/opt_debug.m:
	Conform to changes.

library/construct.m:
library/store.m:
	Handle double-word constructor arguments.

runtime/mercury_conf.h.in:
	Clarify what `MR_BOXED_FLOAT' now means.

runtime/mercury_float.h:
	Add helper macros for converting between doubles and word/dwords.

runtime/mercury_deconstruct.c:
runtime/mercury_deconstruct.h:
	Add a macro `MR_arg_value' and a helper function to extract a
	constructor argument value.  This replaces `MR_unpack_arg'.

runtime/mercury_type_info.h:
	Remove `MR_unpack_arg'.

	Document that MR_DuArgLocn.MR_arg_bits may be -1.

runtime/mercury_deconstruct_macros.h:
runtime/mercury_deep_copy_body.h:
runtime/mercury_ml_arg_body.h:
runtime/mercury_table_type_body.h:
