Unlike the C++ FE, the C FE ignored pragmas (as if they weren't there) in
pragma_stmt contexts if c*_parser_pragma returns false only when after labels,
not inside of substatements of selection or loop statements.
After making just that change, several gomp/goacc testcases started failing,
because extra diagnostics has been emitted (in C, in C++ it was emitted
already before). Say
void
foo (int x)
{
if (x)
#pragma omp barrier
}
used to in C emit just an error that the pragma is not allowed in such
contexts, but in C++ emitted both that and a parsing error that
if (x)
}
is invalid. So, the rest of this patch is mostly about returning true
after we report that that certain pragma is not allowed in pragma_stmt
contexts, because for error-recovery it seems better to treat the
pragma in that case as something that is the substatement of such if etc.
c*_parser_pragma return value is only ever used for pragma_stmt context,
in which false means act as if the pragma isn't there (e.g. has been handled
already by preprocessor etc.), and true which means it was there.
