Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.
Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

- Fix bug 3185, with misc other cleanups.
- Needed to implement SPUInstrInfo::InsertBranch(). CAUTION: Not sure what
gets or needs to get passed to InsertBranch() to insert a conditional
branch. This will abort for now until a good test case shows up.

that merely add passes. This allows them to be used with either
FunctionPassManager or PassManager, or even with a custom new
kind of pass manager.
