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.

f5bb45f895 Note ARM constant island alignment in the release notes. 
The command line option should be removed, but not until the feature has
gotten a lot of testing. The ARMConstantIslandPass tends to have subtle
bugs that only show up after a while.

10e412ec6b The saved registers weren't being processed in the correct order. This lead to 
the compact unwind claiming that one register was saved before another, which
isn't all that great in general. Process them in the natural order. Reverse the
list only when necessary for the algorithm.

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.
