[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

[OpenMP] Lower taskyield using OpenMP IR Builder This is similar to D69828. Special codegen for enclosing untied tasks is still done in clang. Differential Revision: https://reviews.llvm.org/D70799

[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

[OPENMP] Codegen for 'taskyield' directive For 'taskyield' directive emit call to kmp_int32 __kmpc_omp_taskyield(ident_t *, kmp_int32 global_tid, int end_part); runtime function call with end_part arg set to 0 (it is ignored). Differential Revision: http://reviews.llvm.org/D7047 llvm-svn: 228272
