[OPENMP] Fix for LCV in simd directives in explicit clauses. If loop control variable for simd-based directives is explicitly marked as linear/lastprivate in clauses, codegen for such construct would crash. Patch fixes this problem. llvm-svn: 267101

[OPENMP] Support for -fopenmp-simd option with compilation of simd loops only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560

[CodeGen] Generate llvm.loop.parallel_accesses instead of llvm.mem.parallel_loop_access metadata. Instead of generating llvm.mem.parallel_loop_access metadata, generate llvm.access.group on instructions and llvm.loop.parallel_accesses on loops. There is one access group per generated loop.
