PR target/20561
* cfglayout.c (reemit_insn_block_notes): Don't put block notes in
between jump table and its label.
* final.c (shorten_branches): Handle notes in between ADDR_VEC
resp. ADDR_DIFF_VEC and the label preceeding it.
(final_scan_insn): Likewise. Ensure ADDR_VEC resp. ADDR_DIFF_VEC
is emitted in the right section.
* gcc.dg/20050321-2.c: New test.
