re PR debug/54953 (New sra-1.c FAILs on powerpc)
PR debug/54953
* 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.
