* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-2949-132/+216

* Second attempt:Bill Wendling2009-04-2949-191/+227
| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70343 91177308-0d34-0410-b5e6-96231b3b80d8
