ae749a9bb5 Correctly Expand or Promote FP_TO_UINT based on the capabilities of the 
machine.  This allows us to generate great code for i32 FP_TO_UINT now on
targets with 64 bit extensions.

b7f6ef12f6 Allow custom lowered FP_TO_SINT ops in the check for whether a larger 
FP_TO_SINT is preferred to a larger FP_TO_UINT.  This seems to be begging
for a TLI.isOperationCustom() helper function.

39387a5c93 Handle allocations that, even after removing dead uses, still have more than 
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.

18e78bb09e Fix a bug where we would 'promote' an allocation from one type to another 
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.

b53c2382a9 Before promoting a malloc type, remove dead uses. This makes instcombine 
more effective at promoting these allocations, catching them earlier in the
compile process.
