Take a look at the usage of INSN_ANNULLED_BRANCH_P in pa/pa.md.  It's
used to check whether a branch should be annulled or not.

The INSN_ANNULLED_BRANCH_P and INSN_FROM_TARGET_P apply to active insns
as determined by active_insn_p.  It appears the usage of the unchanging
flag changes with compiler pass :-(

Maybe these two macros shouldn't be checked.
