c++/modules: Improve errors for bad module-directives [PR115200]
This fixes an ICE when a module directive is not given at global scope.
Although not explicitly mentioned, it seems implied from [basic.link] p1
and [module.global.frag] that a module-declaration must appear at the
global scope after preprocessing. Apart from this the patch also
slightly improves the errors given when accidentally using a module
control-line in other situations where it is not expected.
PR c++/115200
gcc/cp/ChangeLog:
* parser.cc (cp_parser_error_1): Special-case unexpected module
directives for better diagnostics.
(cp_parser_module_declaration): Check that the module
declaration is at global scope.
(cp_parser_import_declaration): Sync error message with that in
cp_parser_error_1.
gcc/testsuite/ChangeLog:
* g++.dg/modules/mod-decl-1.C: Update error messages.
* g++.dg/modules/mod-decl-6.C: New test.
* g++.dg/modules/mod-decl-7.C: New test.
* g++.dg/modules/mod-decl-8.C: New test.
