[PATCH] D47480: clang-cl: Expose -no-canonical-prefixes

[Takuto Ikuta via Phabricator via cfe-commits]

takuto.ikuta added a comment.

On windows, argv0 is changed to absolute path before we call GetExecutablePath.
That makes resource-dir absolute.
I need clang-cl on windows has relative --resource-dir.

See around heres.
