All in-tree users of shorten_branches now pass in an rtx_insn *, so we
can eliminate the cast from rtx.
gcc/
* output.h (shorten_branches): Strengthen param from rtx to
rtx_insn *.
* final.c (shorten_branches): Likewise, renaming param back from
"uncast_first" to "first", and dropping the checked cast from rtx
to rtx_insn *.
* genattr.c (gen_attr): Likewise when writing out the prototype of
shorten_branches.
