(matcher for SFmode inequality comparison): Use cmfe, not cfm.

Browse Source 
(matchers for {store-flag, not-store-flag, neg-store-flag}): Output
if-false instruction first before if-true instruction.
(matcher for (AND store-flag x)): Only match if reversible_cc_register.
(matcher for (IF-THEN-ELSE reg (NOT reg))): Likewise.
