poly_int: omp-simd-clone.c

Browse source 
This patch adds a wrapper around TYPE_VECTOR_SUBPARTS for omp-simd-clone.c.
Supporting SIMD clones for variable-length vectors is post GCC8 work.

gcc/
	* omp-simd-clone.c (simd_clone_subparts): New function.
	(simd_clone_init_simd_arrays): Use it instead of TYPE_VECTOR_SUBPARTS.
	(ipa_simd_modify_function_body): Likewise.
