This patch uses target-insns.def to define casesi and tablejump.
It's the first point in the series at which we need access to the
instruction code, so the patch adds that to targetm as well.

Bootstrapped & regression-tested on x86_64-linux-gnu and aarch64-linux-gnu.
Also tested via config-list.mk.  OK to install?

Thanks,
Richard
