agx: Mark the logical ends of blocks
...
We need to insert parallel copies at the logical end of blocks, before branches.
Add a pseudo instruction signaling that. Cribbed from ACO.

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

agx: Use correct types for some IR enums
...
Otherwise there are implicit int->enum casts which prevent us from building as
C++ (with -fpermissive).

Sets the output sample mask to a given 8-bit immediate or 16-bit
