[clang] c64ca93 - clang: Treat ieee mode as the default for denormal-fp-math

[Jeremy Morse via cfe-commits]

Hi Matt,

FYI several build bots tripped on this commit:

      http://lab.llvm.org:8011/builders/clang-x86_64-debian-fast/builds/24703/
      http://lab.llvm.org:8011/builders/clang-cmake-x86_64-avx2-linux/builds/13465/
      http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/15994/

I've reverted the commit in 737394c490444e968a6f640b99a6614567ca7f28
to clear the bots.
