* expr.c (expand_expr_real_1): Just use do_store_flag.
(do_store_flag): Drop support for TRUTH_NOT_EXPR. Use
emit_store_flag_force.
* expmed.c (emit_store_flag_force): Copy here trick
previously in expand_expr_real_1. Try reversing the comparison.
(emit_store_flag_1): Work if target is NULL.
(emit_store_flag): Work if target is NULL, using the result mode
from the comparison. Use split_comparison, restructure final part
to simplify conditionals.
