Reverted in r278814, it appears to break usage of _xgetbv on Windows:
https://build.chromium.org/p/chromium.fyi/builders/ClangToTWin%28dll%29/builds/5846/steps/compile/logs/stdio
../../base/cpu.cc(194,10): error: use of undeclared identifier '_xgetbv'
(_xgetbv(0) & 6) == 6 /* XSAVE enabled by kernel */;
You removed the test in ms-intrin.cpp that would have prevented this
breakage, too.
