c/c++, asm: Use nicer error for const and restrict
Not all qualifiers are asm qualifiers. We can talk about that in a
nicer way than just giving a generic parser error.
This also adds two testcases for C++, that previously were for C only.
c/
* c-parser.c (c_parser_asm_statement) <RID_CONST, RID_RESTRICT>: Give
a more specific error message (instead of just falling through).
cp/
* parser.c (cp_parser_asm_definition) <RID_CONST, RID_RESTRICT>: Give
a more specific error message (instead of just falling through).
testsuite/
* g++.dg/asm-qual-1.C: New testcase.
* g++.dg/asm-qual-2.C: New testcase.
* gcc.dg/asm-qual-1.c: Update.
