b5e6a4a74d Fixed stack objects do not specify alignments, but their offsets are known. 
Use that information when doing the transformation to merge multiple loads
into a 128-bit load.

8f95262124 Switch to a very conservative heuristic for determining when loop-unswitching 
will be profitable.  This is mainly to remove some cases where excessive
unswitching would result in long compile times and/or huge generated code.

Once someone comes up with a better heuristic that avoids these cases, this
should be switched out.
