Mike Rice f90abac6ca [OpenMP] Use compound operators for reduction combiner if available.
The OpenMP spec seems to require the compound operators be used for
+, *, &, |, and ^ reduction.  So use these if a class has those operators.
If not try the simple operators as we did previously to limit the impact
to existing code.

Alexey Bataev 8a8c69808c [OPENMP]Add support for analysis of reduction variables.
Summary:
Reduction variables are the variables, for which the private copies
must be created in the OpenMP regions. Then they are initialized with
the predefined values depending on the reduction operation. After exit
from the OpenMP region the original variable is updated using the
reduction value and the value of the original reduction variable.

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
on target- and trask-based directives.

Joel E. Denny d2649292ef [OpenMP] Refactor const restriction for reductions
As discussed in D56113, this patch refactors the implementation of the
const restriction for reductions to reuse a function introduced by
D56113.  A side effect is that diagnostics sometimes now say
"variable" instead of "list item" when a list item is a variable.
