Analyze has to be before checking the condition, obviously. Properly construct an iterator for prior.

Support spill comments.

Have the asm printer emit a comment if an instruction is a spill or
reload and have the spiller mark copies it introdues so the asm printer
can also annotate those.

Special case FixedStackPseudoSourceValueVal as well. Do we really need to differentiate PseudoSourceValueVal from FixedStackPseudoSourceValueVal at this level?

- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)
lwc1 $f0, %lo($CPI1_0)($2)

Make sure when ProcessImplicitDefs removes a copy which kills its source reg that it
removes the copy from said reg's Kills list.

Fix for the original bug in PR5495 - Look at uses as well as defs when determining the PHI-copy insert point.

- Patch by Andrew Canis!

conservatively. eliminateFrameIndex() machinery adjust to handle addr mode
6 (vld1/vst1) used for spills. Fix tests to expect aligned Q-reg spilling

This allows JT to eliminate a ton of infeasible edges when

zext(icmp). It may be able to optimize that away. This fixes one of the cases
