passed.

b0096bd19d Turn loop strength reduction on by default.
Only run createLowerConstantExpressionsPass for the simple isel.  The DAG
isel has no need for it.

3c304a3ba1 Consolidate the GPOpt stuff to all use the Subtarget, instead of still
depending on the command line option.  Now the command line option just
sets the subtarget as appropriate.  G5 opts will now default to on on
G5-enabled nightly testers among other machines.

2) loads

3ea934668b Changes commited for Nate Begeman:
Use a PowerPC specific prolog epilog inserter to control where spilled
callee save regs are placed on the stack.
Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access
globals


Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp
