  Revert "Revert "Modify FPFeatures to use delta not absolute settings""

This reverts commit b55d723ed61052b77e720dcffecac43abe873186.
Reapply Modify FPFeatures to use delta not absolute settings

To solve https://bugs.llvm.org/show_bug.cgi?id=46166 where the
floating point settings in PCH files aren't compatible, rewrite
FPFeatures to use a delta in the settings rather than absolute settings.
With this patch, these floating point options can be benign.
