Fix alignment in teams-reduction.c test

The runtime will use the global kmp_critical_name as a lock and
tries to atomically store a pointer in there. This will fail
if the global is only aligned by 4 bytes, the size of one int32_t
element. Use a union to ensure the global is aligned to the size
of a pointer on the current platform.

Fix PR30890: Reduction across teams hangs

__kmpc_reduce_nowait() correctly swapped the teams for reductions
in a teams construct. Apply the same logic to __kmpc_reduce() and
__kmpc_reduce_end().
