Fix post-reload predicate mismatch ICE during qt build:
* config/arc/predicates.md (extend_operand): During/after reload,
allow const_int_operand.
* config/arc/arc.md (mulsidi3_700): Use extend_operand predicate.
(umulsidi3_700): Likewise. Change operand 2 constraint back to "cL".
(mulsi3_highpart): Change operand 2 constraint alternatives 2 and 3
to "i".
(umulsi3_highpart_i): Likewise.
