* c-decl.c (grokdeclarator): Only pedwarn for qualified void

warnings on -pedantic. Update comments.
(start_function): Only copy function type from previous prototype
declaration if return types are compatible.
* c-typeck.c (function_types_compatible_p): Don't condition
warning for incompatibility of volatile qualifiers on the return
type on -pedantic. Update comment.
* doc/invoke.texi (-Wreturn-type, -Wextra): Update.
testsuite:
* gcc.dg/noreturn-5.c: Test qualifiers on function type instead of
on return type.
* gcc.dg/qual-return-1.c: Use -Wreturn-type. Update expected
messages.
* gcc.dg/qual-return-2.c: Update expected messages.
