openmp: -fopenmp-simd fixes [PR98187]

This patch fixes two bugs in the -fopenmp-simd support.  One is that
in C++ #pragma omp parallel master would actually create OMP_PARALLEL
in the IL, which is a big no-no for -fopenmp-simd, we should be creating
only the constructs -fopenmp-simd handles (mainly OMP_SIMD, OMP_LOOP which
is gimplified as simd in that case, declare simd/reduction and ordered simd).

The other bug was that #pragma omp master taskloop simd combined construct
contains simd and thus should be recognized as #pragma omp simd (with only
the simd applicable clauses), but as master wasn't included in
omp_pragmas_simd, we'd ignore it completely instead.

	PR c++/98187
	* c-pragma.c (omp_pragmas): Remove "master".
	(omp_pragmas_simd): Add "master".

	* parser.c (cp_parser_omp_parallel): For parallel master with
	-fopenmp-simd only, just call cp_parser_omp_master instead of
	wrapping it in OMP_PARALLEL.

	* c-c++-common/gomp/pr98187.c: New test.
