agx: Use pseudo ops for mov/not/and/xor/or

Browse Source 
Rather than using builder magic (implicitly lowered on emit), add actual pseudo
operations (explicitly lowered before encoding). In theory this is slower, I
doubt it matters. This makes the instruction aliases first-class for IR prining
and machine inspection, which will make optimization passes easier to write.
