This patch adds OMPIRBuilder support for the simdlen clause for the simd directive. It uses the simdlen support in OpenMPIRBuilder when it is enabled in Clang. Simdlen is lowered by OpenMPIRBuilder by generating the loop.vectorize.width metadata. Reviewed By: jdoerfert, Meinersbur Differential Revision: https://reviews.llvm.org/D129149
