Don't build examples by default, use BUILD_EXAMPLES=1 to build them. The only utility of this is testing that we keep the examples up to date, I will just make the buildbots run with this flag.

- Check memoperand alignment instead of checking stack alignment. Most load / store folding instructions are not referencing spill stack slots.
- Mark MOVUPSrm re-materializable.

Fix an expensive-checks error.

The Mask and LHSMask may not be of the same size, so don't do the
transformation if they're different.

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

parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler).  Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.

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.
