This adds and entry for `MOVcc_ru6` (e.g. `mov.eq  %r0, 32`) in `ARCInstrInfo.td`, its associated dependencies, and the ability to decode this instruction from an object file.

For example, when disassembling the object file derived from compiling:

  int f(int x) {
    return __builtin_clz(x);
  }

we used to have:

  00000000 <f>:
         0: 2f 28 13 80   <unknown>
         4: ca 20 21 08   <unknown>
         8: e0 7f         j_s.d   [%blink]
         a: ce 20 e2 07   <unknown>

but now we have:

  00000000 <f>:
         0: 2f 28 13 80   <unknown>
         4: ca 20 21 08   mov.eq  %r0, 32
         8: e0 7f         j_s.d   [%blink]
         a: ce 20 e2 07   <unknown>
