Bug 23037 – importC: type with only type-qualifier doesn't work

const a; // ignored, doesn't declare "a" const b = 1; // syntax error int c = sizeof(const); // segfault in src/dmd/expression.d:3397 int d = (const)0; // segfault in src/dmd/mtype.d:2710 int *e = (const*)0; // segfault in src/dmd/mtype.d:4050 enum E : const { ee=1, }; // assert in src/dmd/dsymbolsem.d:2164 depending on what C11 allows, these should be either rejected in the parser or made to default to "int" like in other compilers the line numbers are at dmd commit 41ca11ebf3cc9086906958ea448b69bf37dc36a0

C11 6.7.2-4 says "At least one type specifier shall be given in the declaration specifiers in each declaration" I'll go with that.
