The clang-x64-windows-msvc buildbot is failing after 707447159341f7b5678dee4f47731af50524b9ae due to this test failing: https://lab.llvm.org/buildbot/#/builders/63/builds/8528 This is a stab in the dark, but my first thought is that it may be due to the handling of floats with MSVC or something. So this removes the floating point part of the check. I don't have access to a Windows machine handy to debug this just yet, so pushing this to see if it can quickly return the buildbot to green.
