[PATCH] D81795: [clang] Enable -mms-bitfields by default for mingw targets

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Seems reasonable; GCC is the "system compiler" for this platform.   Does `isWindowsGNUEnvironment` exactly track the condition that GCC uses?  It's just MinGW, not Cygwin?
