Alexey Bataev 27ef9518de [OPENMP]Improve detection of omp_allocator_handle_t type and predefined 
allocators.

It is better to deduce omp_allocator_handle_t type from the predefined
allocators, because omp.h header might not define it explicitly. Plus,
it allows to identify the predefined allocators correctly when trying to
build the allcoator for the global variables.

Alexey Bataev 282555ad82 [OPENMP]Warn if the different allocator is used for the variable. 
If the allocator was specified for the variable and next one is found
with the different allocator, the warning is emitted, and the allocator
is ignored.

Alexey Bataev d2fc965f1b [OPENMP]Check that global vars require predefined allocator. 
According to OpenMP, 2.11.3 allocate Directive, Restrictions, C / C++,
if a list item has a static storage type, the allocator expression in
  the allocator clause must be a constant expression that evaluates to
  one of the predefined memory allocator values. Added check for this
  restriction.
