Use first position in LAllocator ordering heuristic. · 915f9ea5

mstarzinger@chromium.org authored May 03, 2013

This changes the tiebreaker for LAllocator's ordering heuristic of
live ranges to use the first use position instead of the first hinted
use position. Searching for the first hinted position introduces
unnecessary overhead.
