There's more variation that we need to handle. Error checking will need
to be on operand predicates.

f9aabb8f32 Don't adjust for alignment padding in OffsetIsInRange.
This adjustment is already included in the block offsets computed by
BasicBlockInfo, and adjusting again here can cause the pass to loop.

When CreateNewWater splits a basic block, OffsetIsInRange would reject
the new CPE on the next pass because of the too conservative alignment
adjustment. This caused the block to be split again, and so on.

299b059cd6 Consider CPE alignment in CreateNewWater().
An aligned constant pool entry may require extra alignment padding where
the new water is created.  Take that into account when computing offset.

Also consider the alignment of other constant pool entries when
splitting a basic block.  Alignment padding may make it necessary to
move the split point higher.

020f4106f8 Model ARM predicated write as read-mod-write. e.g.
r0 = mov #0
r0 = moveq #1

Then the second instruction has an implicit data dependency on the first
instruction. Sadly I have yet to come up with a small test case that
demonstrate the post-ra scheduler taking advantage of this.

to finalize MI bundles (i.e. add BUNDLE instruction and computing register def
  and use lists of the BUNDLE instruction) and a pass to unpack bundles.
- Teach more of MachineBasic and MachineInstr methods to be bundle aware.
- Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to
  prevent IT blocks from being broken apart.
