Fix a bug where the Mercury calls C++ sample was not linking with the
C++ library. This worked, because the sample didn't actually make use
of the C++ library, but failed as soon as users tried to extend the
sample to use with their real C++ programs.
samples/c_interface/mercury_calls_cplusplus/cpp_main.cc:
Use the C++ standard library's stream I/O, rather than printf().
samples/c_interface/mercury_calls_cplusplus/Mmakefile:

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.
compiler/hlds_pred.m:
Add a new pred_marker which indicates whether or not a
predicate can only be accessed by its fully qualified name.

Allow user-defined operator precedence tables for parser__read_term
and term_io__write_term.
library/ops.m:
Define a typeclass `op_table' with methods for accessing
operator precedence tables.
Define a type `ops__mercury_op_table', representing the
standard Mercury operator table.
Make `ops__mercury_op_table' an instance of `op_table'.
Define `ops__table' as equivalent to `ops__mercury_op_table'
(it's obsolete, but we can't mark types as obsolete).
Rename `ops__init_op_table' as `ops__init_mercury_op_table',
mark ops__init_op_table as obsolete
library/parser.m:
library/term_io.m:
Add variants of `parser__read_term' and `term_io__write_term'
which take an operator precedence table.
Don't hard-code the maximum priority and argument priority.
Use the `op_table' methods to find those.
Make the priority of operator terms (X `op` Y) 1, not 100.
The reference manual states that operator terms have
the highest precedence possible.
This change slows down a program which does nothing but
parse terms by a bit under 5%, less for writing.

operator terms now have the lowest possible priority.
`rem' is an operator -- it doesn't need backquotes.

Added a field to the module_sub_info to hold information about
user-requested type specializations, filled in by make_hlds.m
and not used by anything after higher_order.m.
compiler/make_hlds.m:
For each `:- pragma type_spec' declaration, introduce a new predicate
which just calls the predicate to be specialized with the
specified argument types. This forces higher_order.m to produce
the specialized versions.
compiler/higher_order.m:
Process the user-requested type specializations first to ensure
that they get the correct names.
Allow partial matches against user-specified versions, e.g.
map__lookup(map(int, list(int)), int, list(int)) matches
map__lookup(map(int, V), int, V).
Perform specialization where a typeclass constraint matches a
known instance, but the construction of the typeclass_info is

library/private_builtin.m:
Added `instance_constraint_from_typeclass_info/3' to extract
the typeclass_infos for a constraint on an instance declaration.
This is useful for specializing class method calls.
Added `thread_safe' to various `:- pragma c_code's.
Added `:- pragma inline' declarations for `builtin_compare_*', which
are important for user-guided type specialization. (`builtin_unify_*'
are simple enough to go in the `.opt' files automatically).
compiler/polymorphism.m:
`instance_constraint_from_typeclass_info/3' does not need type_infos.
Add `instance_constraint_from_typeclass_info/3' to the

can interpret.
