Alexey Bataev 68d230359a [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.

Alexey Bataev f66517edc4 [OPENMP] Fix for PR34398: assert with random access iterator if the
step>1.

If the loop is a loot with random access iterators and the iteration
construct is represented it += n, then the compiler crashed because of
reusing of the same MaterializedTemporaryExpr around N. Patch fixes it
by using the expression as written, without any special kind of
wrappings.

Alexey Bataev 6a092ca245 [OPENMP] Remove extra code transformation.
For better support of some specific GNU extensions some extra
transformation of AST nodes were introduced. These transformations are
very hard to handle. The code is improved in handling of these
extensions by using captured expressions construct.

Alexey Bataev ee1775e00f [OPENMP] Do not allow to use threadprivate or thread local variables as loop iteration variables.
According to OpenMP the loop iteration variable may not appear in a threadprivate directive.
