[Bug optimization/15296] New: Delayed branch scheduling causing invalid code on cris-*

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

reorg.c messes up register liveness info by deleting its own
placeholder insns.  Further analysis with forthcoming patch.
First seen in 3.2.x.  On 3.3-branch, 3.4-branch the problem
is exposed by the to-be-attached test-case but it's hidden
on trunk.
