[Parser] Emit descriptive diagnostic for misplaced pragma

Authored by sepavloff on Jul 18 2019, 9:47 AM.



If a class or struct or union declaration contains a pragma that
is not valid in this context, compiler issues generic error like
"expected member name or ';' after declaration specifiers". With this
change the error tells that this pragma cannot appear in this declaration.

The right way to do this is to make a PRAGMA_ANNOTATION macro in TokenKinds.def that defaults to ANNOTATION, like that file already does with e.g. CXX11_KEYWORD. But for future reference, there's also a StringRef::startsWith.
