Alex Zinenko 72d013dd73 [mlir] OpenMP-to-LLVM: properly set outer alloca insertion point ...

Previously, the OpenMP to LLVM IR conversion was setting the alloca insertion
point to the same position as the main compuation when converting OpenMP
`parallel` operations. This is problematic if, for example, the `parallel`
operation is placed inside a loop and would keep allocating on stack on each
iteration leading to stack overflow.
