[Jongwon Lee via llvm-commits]

JongwonLee added a comment.

This patch was motivated by performance improvement in commercial benchmark. 
However, this patch has different tendency in SPEC and LLVM test-suite.
In SPEC benchmark, compile-time increases by about 10 %. In LLVM test-suite, compile-time decreases by about 0.02 %. Execution time has no regression in both SPEC and LLVM test-suites (0.04% and 0.37% improvement respectively). The data are measured from the average of three times executions.
