* final.c (cleanup_subreg_operands): New function.
(final_scan_insn): Use it.
(alter_subreg): Clear the "used" field when we turn a SUBREG into
a REG.
* reload1.c (reload): Delete CLOBBER insns and also cleanup SUBREG
operands when reload has finished.
* reload.h (cleanup_subreg_operands): Declare..
* flow.c (life_analysis_1): No longer delete CLOBBER insns after
reload. Handled in reload itself.
Should fix sh, sparc and probably other problems with post-reload life pass
and scheduling interactions.
