[PATCH] D18594: CodeGen: Add a stand-alone hazard recognizer pass

[Tom Stellard via llvm-commits]

tstellarAMD created this revision.
tstellarAMD added reviewers: atrick, hfinkel.
tstellarAMD added a subscriber: llvm-commits.

This new pass allows targets to use the hazard recognizer without having
to also run one of the schedulers.  This is useful when compiling with
optimizations disabled for targets that still need noop hazards
to be handled correctly.
