[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]Initial fix PR42392: Improve -Wuninitialized warnings for OpenMP programs. Summary: Some OpenMP clauses rely on the values of the variables. If the variable is not initialized and used in OpenMP clauses that depend on the variables values, it should be reported that the uninitialized variable is used in the OpenMP clause expression. This patch adds initial processing for uninitialized variables in OpenMP constructs. Currently, it checks for use of the uninitialized variables in the structured blocks.
