You can use multipliers and dividers from the Arithmetic library, with
a constant 2 fed in as input. This doesn't handle the sra case though
but don't worry too much about it.

So, assuming we're building a test circuit using our ALU compared with
anotherALU built from library subcircuits, I have no idea what to test my shifters
against, other than building my own shifter circuits again. Is there an
against, other than building my own shifter circuits again. Is there an
way to build _input_*2^shamt and _input_/2^shamt that I'm not seeing? Any
otherideas?
This may not work for all cases, but you could use the multiplier circuitincluded in arithmetic to simulate shifting by multiplying by 2 each time,
dividing to shift in the opposite direction. You might get some weird results
though when digits start to drop off the ends...
I was thinking of doing that, but I couldn't figure out how to multiply by 2 athough when digits start to drop off the ends...
