Add an alignment test to check that aligned alloca's really do get
correctly aligned. Some targets may not ensure SP is always a multiple
of STACK_BOUNDARY (particularly with outgoing arguments), which means
aligned alloca does not get correctly aligned. This can be fixed either
by aligning the outgoing arguments or setting STACK_BOUNDARY correctly.
