* cfgrtl.c (can_fallthru): Reorder code to move tablejump check up.
Make that check explicit. BB_HEAD cannot be NULL, remove check for it.
* haifa-sched.c (ready_remove_first_dispatch): Check INSN_P before
looking at INSN_CODE.
* reload1.c (delete_dead_insn) Do not expect JUMP_TABLE_DATA to be an
active_insn_p object, respect basic block boundaries.
* reorg.c (follow_jumps): Use invariant that JUMP_TABLE_DATA always
follows immediately after the jump table data label.
* config/nds32/nds32.c (nds32_output_casesi_pc_relative): Likewise.
* config/sh/sh.c (barrier_align): Likewise. Rearrange code such
that JUMP_TABLE_DATA is not expected to be an active_insn_p object.
