i965/fs: Preserve CFG in predicated break pass.
Operating on this code,
B0: ...
cmp.ne.f0(8)
(+f0) if(8)
B1: break(8)
B2: endif(8)
We can delete B2 without attempting to merge any blocks, since the
break/continue instruction necessarily ends the previous block.
After deleting the if instruction, we attempt to merge blocks B0 and B1.
