Subject: [PATCH] Revert "mesa: remove FLUSH_VERTICES() in _mesa_MatrixMode()"

This reverts commit 0de5e0f3fb0f3671a3ecec6ab4473f9131ecd0ae.

Michel Dänzer spotted two piglit regressions from the change.  I suspect
that removing the FLUSH_VERTICES() actually exposed a bug elsewhere but
I don't have time to hunt down the root issue at this time.
