    loop-invariant: JUMP_INSNs aren't loop invariant [PR97954]

    The following testcase ICEs because loop invariant motion moves asm goto
    with a single output as invariant.
    Normally, jumps aren't really moved, because if they are single set,
    they have their SET_DEST (pc) and pc_rtx has VOIDmode on which one of t=
he
    functions find_invariant_insn calls bails out.  The code already punts =
on
    insns that can throw or trap.  And for asm goto without outputs, it isn=
't
    single set, or asm goto with two or more outputs it isn't single set
either.
