The jump should reference the table directly (as well). Quite
a few targets use pc-relative loads from the jump table, and
so there *is* no load separate from the jump insn.
Anyway, the simplest way out for VAX, should anyone care about
it ever again, is simply to emit a jump directly after the
case instruction. Which lets us kill CASE_DROPS_THROUGH, since
the logical unit of the two now doesn't drop through.
