@ab @rjmccall @mibintc Posted D79730 <https://reviews.llvm.org/D79730> for consideration.
@mibintc can you produce a version of _this_ diff that works with D79730 <https://reviews.llvm.org/D79730> applied. Currently the following fail, as they do on Apple Master:

  Failing Tests (4):
    Clang :: CodeGen/finite-math.c
    Clang :: CodeGen/fp-floatcontrol-stack.cpp
    Clang :: CodeGenOpenCL/relaxed-fpmath.cl
    Clang :: Frontend/diagnostics-order.c

> @rjmccall Uncertain how to proceed, can you recommend?  If I recall correctly, I added the lines in CompilerOptions because there were many failing lit tests, i could have fixed the lit fails by adding the lang options to the lit tests. (of course that change could have other repercussions)
