Alexey Bataev 25569296c6 [OPENMP]Add support for analysis of firstprivate variables.
Summary:
Firstprivate variables are the variables, for which the private copies
must be created in the OpenMP regions and must be initialized with the
original values. Thus, we must report if the uninitialized variable is
used as firstprivate.

Alexey Bataev 1242d8f333 [OPENMP]Improve analysis of implicit captures.
If the variable is used in the OpenMP region implicitly, we need to
check the data-sharing attributes for such variables and generate
implicit clauses for them. Patch improves analysis of such variables for
better handling of data-sharing rules.

Alexey Bataev 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

Alexey Bataev b358f9922a [OPENMP] Do not allow variables to be first|last-privates in
distribute directives.
