(subst, case NOT): If STORE_FLAG_VALUE==-1, treat an ASHIFTRT of just the sign bit as if it were an LT.
(subst, case NOT): If STORE_FLAG_VALUE==-1, treat an ASHIFTRT of just the
sign bit as if it were an LT.
(subst, case XOR): Likewise for STORE_FLAG_VALUE==1 and an LSHIFTRT.
(simplify_and_const_int, case LSHIFTRT): If shifting a sign bit copy,
start shift at the sign bit.
(simplify_shift_const): Likewise for ASHIFTRT.
(BYTE_LOADS_EXTEND): Fix typo when defining.
(setup_incoming_promotions): Set modes properly.
