Kudos to Rob for suggesting that I add this important step.

one use (but one is a cast).  This handles the very common case of:

 X = alloc [n x byte]
 Y = cast X to somethingbetter
 seteq X, null

In order to avoid infinite looping when there are multiple casts, we only
allow this if the xform is strictly increasing the alignment of the
allocation.

where the second has less alignment required.  If we had explicit alignment
support in the IR, we could handle this case, but we can't until we do.

more effective at promoting these allocations, catching them earlier in the
compile process.

GCC 4.1.  I tried it with 4.0 and 3.3 and it seems fine.
