set of flags that it passes to the linker in order to link against a
selected set of Mercury libraries (the standard libraries plus any others
specified via the --ml option) in the current grade.
This removes the need for using the ml script with standalone interfaces.

use that script!)

Remove support for automatic initialisation of solver types from the language.
This is being done because:
* the current implementation of automatic initialisation means we cannot
support polymorphic solver types, e.g. you cannot have the type foo(bar)
where:
:- solver type foo(T).
:- solver type bar.
* the current initialisation strategy is fairly ad-hoc anyway; in particular
it has a tendency to unnecessarily change the determinism of procedures.
* mode error messages are often quite poor because of the interaction between
automatic initialisation and impure code.
* automatic initialisation is not used in practice. All of the
G12 solver libraries that use solver types recommend explicitly
initialising solver variables.
This change removes support for automatic solver initialisation from the
language. The code for supporting it remains in the implementation, but
it is now dependent upon the developer-only `--solver-type-auto-init'
option.
As a transitional measure the compiler will still accept
`initialisation is ...' attributes in solver type definitions even when
`--no-solver-type-auto-init' is enabled. After this change has bootstrapped,
and the relevant updates have been made to the G12 solver libraries, this
will be changed so that `initialisation is ...' attributes are considered
a syntax error unless `--solver-type-auto-init' is enabled.
doc/reference_manual.texi:
Document that solver type definitions no longer allow initialisation
predicates to be supplied. (The section documenting initialisation
predicates has been commented out rather than deleted since the
implementation of automatic initialisation still exists.)
Remove the section documenting the restrictions on polymorphic
solver types. These restrictions no longer apply in the absence
of automatic initialisation.
compiler/options.m:
Add a new developer-only option, `--solver-type-auto-init', that
controls whether automatic initialisation of solver variables is
allowed (for those solver types that have initialisation predicates
specified.)
compiler/prog_data.m:
Add a type that represents whether a solver type allows automatic
initialisation or not.

Move the all-solutions predicates into their own module, solutions.m.
For now there are (obsolete) forwarding predicates from this module to

Move semidet_succeed, semidet_fail, cc_multi_equal and dynamic_cast

purity casts, e.g. in solver implementations.

Fix a performance bug where dead_pred_elim was taking a significant
amount of time to delete entries from the predicate_table. With this
change dead_pred_elim goes from 12 minutes to 55 seconds CPU time in
the IL grade when compiling accumulator.m with
--intermodule-optimization turned on.
compiler/hlds_module.m:
Implement a new predicate, predicate_table_restrict, which
restricts the predicate_table to include only a subset of the
predicates.
Rather than deleting all the non-needed entries, this
predicate builds the predicate_table from scratch again, hence
this predicate is only useful when the number of predicates to
keep is significantly less than the number of predicates to
delete.
Change predicate_table_do_insert so that it records in the
pred_info whether or not a predicate can only be accessed by
its fully qualified name, this is needed so that the
predicate_table can be rebuilt correctly.
compiler/dead_proc_elim.m:
Use predicate_table_restrict to restrict the set of pred_ids
in the predicate_table rather than module_info_remove_predicate
as the amount of predicates to keep is in general
significantly smaller than the number of predicates to keep.
