[llvm-mca] Speedup the default resource selection strategy.
This patch removes a (potentially) slow while loop in
DefaultResourceStrategy::select(). A better (and faster) approach is to do some
bit manipulation in order to shrink the range of candidate resources.
On a release build, this change gives an average speedup of ~10%.
