[PATCH] D111952: [clang] [MinGW] Guess the right ix86 arch name spelling as sysroot

[Martin Storsjö via Phabricator via cfe-commits]

mstorsjo added a comment.

I guess a downside of this solution, is that if an `i686` sysroot exists next to the clang binary, it becomes practically impossible to test codegen differences when you run it with various `-target iX86-w64-mingw32` options, as they'd all be corrected back to `i686`. (This wouldn't be an issue if the autodetection was done in `computeTargetTriple` only when the `-m32`/`-m64` options are used though.)
