simd-based constructs without emission of OpenMP runtime calls.

Alexey Bataev db39021cee [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).

Alexey Bataev f33eba6573 [OPENMP] Additional processing of 'omp atomic write' directive.
According to OpenMP standard, Section 2.12.6, atomic Construct, '#pragma omp atomic write' is allowed to be used only for expression statements of form 'x = expr;', where x is a lvalue expression and expr is an expression with scalar type. Patch adds checks for it.
