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.

871aefb9a0 decoder/a64: Tweak ordering algorithm
Ensuring only instruction families are sorted with each other in
the fashion previously devised does not admit a total ordering.

Now that we have unsigned absolute difference capabilities, we can just use this to
append onto the result via a vector add.

701f43d61e IR: Add opcodes for interleaving upper-order bytes/halfwords/words/doublewords
I should have added this when I introduced the functions for interleaving
low-order equivalents for consistency in the interface.

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.
