Don't lint during SuggestedFixes#compilesWithFix

Under certain circumstances this avoids triggering a compiler bug. It is
also expected to speed up the trial compilation somewhat. The implicit
assumption here is that it is okay to suggest a fix which introduces
another warning. (This may not be so in general, but the introduced
warning may be less severe or may be resolved manually.)

See google#849.
