[PATCH 3/4] arc: Use accl_operand predicate for fma instructions.

[Claudiu Zissulescu]

With the refurbish of ARC600' accumulator support, the mlo_operand
doesn't reflect the proper low accumulator register for the newer
ARCv2 accumulator register used by the fma instructions, replace
it with accl_operand predicate.

xxxx-xx-xx  Claudiu Zissulescu  <claz...@synopsys.com>

        * config/arc/arc.md (fmasf4_fpu): Use accl_operand predicate.
        (fnmasf4_fpu): Likewise.
