If the allocator was specified for the variable and next one is found
with the different allocator, the warning is emitted, and the allocator

Alexey Bataev 4f680db257 [OPENMP] Codegen for local variables with the allocate pragma.

__kmpc_alloc|__kmpc_free functions are used for memory (de-)allocation.
