c++/modules: relax diagnostic about GMF contents
Issuing a hard error when the GMF doesn't consist only of preprocessing
directives happens to be inconvenient for automated testcase reduction
via cvise. This patch relaxes this diagnostic into a pedwarn that can
be disabled with -Wno-global-module.
gcc/c-family/ChangeLog:
* c.opt (Wglobal-module): New warning.
gcc/cp/ChangeLog:
* parser.cc (cp_parser_translation_unit): Relax GMF contents
error into a pedwarn.
gcc/ChangeLog:
* doc/invoke.texi (-Wno-global-module): Document.
gcc/testsuite/ChangeLog:
* g++.dg/modules/friend-6_a.C: Pass -Wno-global-module instead
of -Wno-pedantic. Remove now unnecessary preprocessing
directives from GMF.
