471171c4c9 [OPENMP]Add check for undefined behavior with thread allocators on
target and task-based directives.

According to OpenMP 5.0, 2.11.4 allocate Clause, Restrictions, For task,
taskloop or target directives, allocation requests to memory allocators
with the trait access set to thread result in unspecified behavior.
Patch introduces a check for omp_thread_mem_alloc predefined allocator
on target- and trask-based directives.

0dce2ea758 [OPENMP] Use canonical declarations for redeclarations checks.
If the captured variable has some redeclarations we may run into the
situation where the redeclaration is used instead of the canonical
declaration and we may consider this variable as one not captured
before.
