c++: Fix ICE-on-invalid with -Wvexing-parse [PR97881]

This invalid (?) code broke my assumption that if decl_specifiers->type
is null, there must be any type-specifiers.  Turn the assert into an if
to fix this crash.

gcc/cp/ChangeLog:

PR c++/97881
* parser.c (warn_about_ambiguous_parse): Only assume "int" if we
actually saw any type-specifiers.

gcc/testsuite/ChangeLog:

PR c++/97881
* g++.dg/warn/Wvexing-parse9.C: New test.
