    * valtrack.h (DEBUG_TEMP_AFTER_WITH_REG_FORCE): New.
    * valtrack.c (dead_debug_insert_temp): Use emit_debug_insn_after
    even for where == DEBUG_TEMP_AFTER_WITH_REG_FORCE.
    * dce.c (word_dce_process_block, dce_process_block): Pass
    DEBUG_TEMP_AFTER_WITH_REG_FORCE if insn is needed and therefore
    not going to be eliminated.
