Fix an issue where we were reusing materializations of constants in blocks not dominated by the materialization. This is
the simple fix, materializing the constant before every use. It might be better to either track domination of uses or
to materialize all constants and the beginning of the function and let remat sort when to do materialization at uses.

Add a small pass that sets the readnone/readonly
attributes on functions, based on the result of
alias analysis. It's not hardwired to use
GlobalsModRef even though this is the only (AFAIK)
alias analysis that results in this pass actually
doing something. Enable as follows:
opt ... -globalsmodref-aa -markmodref ...
Advantages of this pass: (1) records the result
of globalsmodref in the bitcode, meaning it is
available for use by later passes (currently
the pass manager isn't smart enough to magically
make an advanced alias analysis available to all
later passes), which may expose more optimization
opportunities; (2) hopefully speeds up compilation
when code is optimized twice, for example when a
file is compiled to bitcode, then later LTO is done
on it: marking functions readonly/readnone when
producing the initial bitcode should speed up alias
analysis during LTO; (3) good for discovering that
globalsmodref doesn't work very well :)

Revert the "XFAIL" for the rotate_ops.ll testcase. Instead, mark ISD::ROTR
instructions in CellSPU as "Expand" so that they won't be generated. I added a
"FIXME" so that this hack can be addressed and reverted once ISD::ROTR is
supported in the .td files.

CellSPU doesn't appear to support fully the "ISD::ROTR" operation. The DAG
combiner can now generate ROTR if the backend says that it can handle it. Cell
SPU says this, but gets an error from code gen saying that it can't select
ROTR. I'm xfailing this test until this can be fixed.

Fix an issue where a use might be selected before a def, and then we didn't respect the pre-chosen vreg
assignment when selecting the def. This is the naive solution to the problem: insert a copy to the pre-chosen
vreg. Other solutions might be preferable, such as:
1) Passing the dest reg into FastEmit_. However, this would require the higher level code to know about reg classes, which they don't currently.
2) Selecting blocks in reverse postorder. This has some compile time cost for computing the order, and we'd need to measure its impact.
