[PATCH] D81869: Modify FPFeatures to use delta not absolute settings to solve PCH compatibility problems

[Melanie Blower via Phabricator via cfe-commits]

mibintc updated this revision to Diff 271188.
mibintc added a comment.

This version passes all the lit tests, i believe it's functional tho' maybe not elegant.
I still need to add a test case that PCH behaves as desired, and that the floating point command line options from PCH create do not clobber command line options from compilations that use a pch
