784323cf0f asahi: rip out existing MDI+GS implementation 
I don't love deleting working code without a working replacement. But this impl
is deeply questionable as-is, and will only balloon in complexity for shader
objects. We need to go back to the drawing board with MDI and lower to real
draws, possibly with control stream looping.

Good news is that this is GL so we can prototype all this.

14e1bb78ae agx: add spill/fill lowering pass 
This simple pass turns moves of memory registers (outputted by RA from the
spiller produced moves/phis of memory variables) into concrete stack load/store
instructions. it's a lot more convenient to do this as a dedicated post-RA pass
than trying to fold this into the hairball that is RA proper.

40da539d01 agx: introduce "memory variables" 
in order to spill, we need to be able to assign spill slots. this is equivalent
to register allocation, so we borrow NAK's neat solution: add "memory variables"
into the IR which get RA'd to "memory registers" that correspond directly to
stack slots. then we can just spill by inserting moves.

this requires extensions to RA, parallel copy lowering, and the IR itself. but
it makes competent spilling so much more straightforward.

to exercise this code path, the commit also includes a trivial spiller that
simply moves every source/destination between memory variables and general
variables, which has the effect of spilling everything. to be replaced by
Braun-Hack eventually, this is just foundations.
