[PATCH] Fix emission of jump tables (PR tree-optimization/86263).

[Martin Liška]

Hello.

Quite obvious patch where I accidentally removed check for:
if (!targetm.have_casesi () && !targetm.have_tablejump ())

Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?
Martin
