1f426deade Add nodes for CondCodeSDNode and setcc, and add a bunch of pattern fragments
to make it easy to use them.  This lets you write patterns like:

(set PRRC:$rd, (setne GPRC:$rS, imm:$SH))

and stuff.

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
