Comment (by erikd):

 According to git bisect, the commit that broke PowerPC was:

 {{{
 commit 5d57087e314bd484dbe14958f9b422be3ac6641a
 Author: Thomas Miedema <thomasmiedema at gmail.com>
 Date:   Wed Aug 5 11:31:21 2015 +0200

 Pretty: fix a broken invariant (#10735)
 }}}

 but since that doesn't touch any of the PowerPC specific code, the PowerPC
 code gen problem is simply a by-product of this patch.
