c++: Prune dead functions.
I was looking at the LCOV coverage report for the C++ FE and
found a bunch of unused functions that I think we can remove.
Obviously, I left alone various dump_* and debug_* routines.
I haven't removed cp_build_function_call although it is also
currently unused.
* lambda_return_type: was used in parser.c in GCC 7, unused since r255950,
* classtype_has_non_deleted_copy_ctor: appeared in GCC 10, its usage
was removed in c++/95350,
* contains_wildcard_p: used in GCC 9, unused since r276764,
* get_template_head_requirements: seems to never have been used,
* check_constrained_friend: seems to never have been used,
* subsumes_constraints: unused since r276764,
* push_void_library_fn: usage removed in r248328,
* get_template_parms_at_level: unused since r157857,
* get_pattern_parm: unused since r275387.
(Some of the seemingly unused functions, such as set_global_friend, are
actually used in libcc1.)
gcc/cp/ChangeLog:
* class.c (classtype_has_non_deleted_copy_ctor): Remove.
* constraint.cc (contains_wildcard_p): Likewise.
(get_template_head_requirements): Likewise.
(check_constrained_friend): Likewise.
(subsumes_constraints): Likewise.
* cp-tree.h (classtype_has_non_deleted_copy_ctor): Likewise.
(push_void_library_fn): Likewise.
(get_pattern_parm): Likewise.
(get_template_parms_at_level): Likewise.
(lambda_return_type): Likewise.
(get_template_head_requirements): Likewise.
(check_constrained_friend): Likewise.
(subsumes_constraints): Likewise.
* decl.c (push_void_library_fn): Likewise.
* lambda.c (lambda_return_type): Likewise.
* pt.c (get_template_parms_at_level): Likewise.
(get_pattern_parm): Likewise.
