4b3d70de5f simd_shift_by_immediate: Factor out common code in shift instructions 
Gets rid of partial duplication of the same code for instructions that only have a small behavior difference to them.

e.g. The only difference between SSHR and SSRA is that SSRA adds an accumulator before storing the result.

40ec25356b A64: NOP immediate variant of PRFM 
Makes behavior identical to the literal variant of PRFM. Given this is simply a hint instruction,
this is valid behavior. The upside is that we don't fall back to Unicorn unnecessarily whenever
the instruction is encountered.

ade595e377 bit_util: Do nothing in RotateRight if the rotation amount is zero 
Without this sanitizing it's possible to perform a shift with a shift
amount that's the same size as the type being shifted. This actually
occurs when decoding ORR variants.

We could get fancier here and make this branchless, but we don't
really use RotateRight in any performance intensive areas.
