Subzero: Improve regalloc performance by optimizing UnhandledPrecolored. A lot of time was being spent in the two loops that check precolored ranges in the Unhandled set, specifically in the endsBefore() check. Solve this by keeping a shadow copy of Unhandled, restricted to the ranges that are precolored. BUG= none R=jvoung@chromium.org Review URL: https://codereview.chromium.org/622553003
