According to the OpenMP standard, compiler must define _OPENMP macro,
which has value in format yyyymm, where yyyy is the year of the standard
and mm is the month of the standard. For OpenMP 5.0 this value must be
set to 201811.

if `-fopenmp-simd` is specified alone, `_OPENMP` macro should not be
defined. If `-fopenmp-simd` is specified along with the `-fopenmp`,
`_OPENMP` macro should be defined with the value `201511`.

only.
Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

OpenMP version.
If '-fopenmp' option is provided '-fopenmp-version=' allows to control,
which version of OpenMP must be supported. Currently it affects only the
value of _OPENMP define.

If target supports TLS all threadprivates are generated as TLS. If target does not support TLS, use runtime calls for proper codegen of threadprivate variables.
