Revert "tcg/i386: Rely on undefined/undocumented behaviour of BSF/BSR"
This reverts commit 4ac76910734209dab83ddd3795f08fc7889ef463.
This fixes
http://lists.nongnu.org/archive/html/qemu-devel/2017-01/msg03062.html
While I think we could get away with relying on the undocumented
behaviour, the tcg constraint system isn't powerful enough to
properly describe the required (non-)overlap conditions.
