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. llvm-svn: 70343
