  [OpenMP][OMPIRBuilder] Use device shared memory for arg structures

Argument structures are created when sections of the LLVM IR corresponding to
an OpenMP construct are outlined into their own function. For this, stack
allocations are used.

This patch modifies this behavior when compiling for a target device and
outlining `parallel`-related IR, so that it uses device shared memory instead
of private stack space. This is needed in order for threads to have access to
these arguments.
