[PATCH] D30183: Add -iframeworkwithsysroot compiler option

[Alex Lorenz via Phabricator via cfe-commits]

arphaman created this revision.

This patch adds support for a new `-iframeworkwithsysroot` compiler option which allows the user to specify a framework path that can be prefixed with the sysroot.

This option is similar to the `-iwithsysroot` option that exists to supplement `-isystem`.
