arc: Fail conditional move expand patterns

If the movcc comparison is not valid it triggers an assert in the
current implementation.  This behavior is not needed as we can FAIL
the movcc expand pattern.

gcc/
* config/arc/arc.cc (gen_compare_reg): Return NULL_RTX if the
comparison is not valid.
* config/arc/arc.md (movsicc): Fail if comparison is not valid.
(movdicc): Likewise.
(movsfcc): Likewise.
(movdfcc): Likewise.
