[PATCH] D19659: [X86] Enable RRL part of the LEA optimization pass for -O2

[Andrey Turetskiy via llvm-commits]

aturetsk added a comment.

Note that the generated test is really LEA-specific, the majority of machine instructions gets modified by the pass. That's why the LEA pass takes ~25% of total compile time in this test.
