poly_int: omp_max_vf
This patch makes omp_max_vf return a polynomial vectorization factor.
We then need to be able to stash a polynomial value in
OMP_CLAUSE_SAFELEN_EXPR too:
/* If max_vf is non-zero, then we can use only a vectorization factor
up to the max_vf we chose. So stick it into the safelen clause. */
For now the cfgloop safelen is still constant though.

gcc/
* omp-general.h (omp_max_vf): Return a poly_uint64 instead of an int.
* omp-general.c (omp_max_vf): Likewise.
* omp-expand.c (omp_adjust_chunk_size): Update call to omp_max_vf.
(expand_omp_simd): Handle polynomial safelen.
* omp-low.c (omplow_simd_context): Add a default constructor.
(omplow_simd_context::max_vf): Change from int to poly_uint64.
(lower_rec_simd_input_clauses): Update accordingly.
(lower_rec_input_clauses): Likewise.
