rs6000: Don't touch below the stack pointer (PR77687)
With the 32-bit SVR4 ABI we don't have a red zone, so we have to restore
the callee-saved registers before we restore the stack pointer.
The previous fix for this PR failed in two ways, for huge frames: first,
we use a negative offset from r11 in that case, so the (mem:BLK 11) access
does no good; second, sched does not handle accesses to mem:BLK correctly
in this case (does not make dependencies).
This patch fixes it by doing a store to (mem:BLK (scratch)) instead.
This means no unrelated (not to stack) loads/stores can be moved over the
stack restore either, but so be it.

The vectoriser was calling vect_get_smallest_scalar_type without

be the intended behaviour: the ultimate test of whether the type

Fix vectorizable_mask_load_store handling of invariant masks
vectorizable_mask_load_store was not passing the required mask type to

defined in the loop, since their STMT_VINFO_VECTYPE will be what we need
anyway. But it's not possible to tell which mask type the caller needs
when looking at an invariant scalar boolean. As the comment above the

In case OP is an invariant or constant, a new stmt that creates a vector def
needs to be introduced. VECTYPE may be used to specify a required type for
vector invariant.
