I did make ENABLE_OPTIMIZED=1 when building llvm, then did:
export PATH=/Volumes/Other/llvm/Release/bin/:$PATH
export CCC=/Volumes/Other/llvm/tools/clang/tools/ccc/ccc
time xcodebuild -parallelizeTargets CC=$CCC LD=$CCC
So I believe that should be with a release build of clang. However, it  
didn't feel as much faster than the debug build I had as I would have  
expected, so I will double check that.

How would I go about using the token cache? Looking at Tools.py, it  
seems to attempt to do some things with it automatically, but it's not  
completely clear to me that what I'm doing would be sufficient to  
trigger that.
