* pa.md (conditional branches): Use the full displacement range
for the branch target. Update length computations to match current

(branch on bit patterns): Likewise.
(decrement_and_branch_until_zero): Re-enable pattern. Rewrite to
be simpler and more efficient. Also handle case where loop counter
is in a FP register.
