[PATCH] D25225: Add an option to save the backend-produced YAML optimization record to a file

[Richard Smith via cfe-commits]

rsmith added a comment.

As discussed on IRC, I have a mild concern about using `-fsave-optimization-record` (with no argument) to enable the feature, and `-fsave-optimization-record=X` to enable the feature and specify a filename; in most (but not all) cases, `-option arg` and `-option=arg` mean the same thing. Other than that, this looks good to me.
