[OPENMP] Fix for PR32333: Crash in call of outlined Function. If the type of the captured variable is a pointer(s) to variably modified type, this type was not processed correctly. Need to drill into the type, find the innermost variably modified array type and convert it to canonical parameter type. llvm-svn: 299868

[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
