c++: Support module language-decl semantics
In modules purview, one can attach a declaration to the global module
(i.e. not the named module in whence the declaration appears), using a
language declaration:
export module Foo;
extern "C++" void *operator new (std::size_t);
This implements those semantics.
gcc/cp/
* parser.cc (cp_parser_linkage_specification): Implement
global module attachment semantics.
gcc/testsuite/
* g++.dg/modules/lang-3_a.C: New.
* g++.dg/modules/lang-3_b.C: New.
* g++.dg/modules/lang-3_c.C: New.
