Alyssa Rosenzweig 86782156e7 asahi: invert geometry shaders
instead of dumping GS outputs to memory and using a GS copy vertex shader,
invert the GS to get a hardware vertex shader to use directly. theoretically,
reduces mem bandwidth at the cost of repeated work if we don't optimze well.
perhaps more importantly, it should reduce heap usage.

Alyssa Rosenzweig 3bd400a2b4 asahi: collapse indirection with GS
1. compile the gs rast program with the rest of the GS. this requires
   duplicating some shader key stuff but this will be improved soon, and
   actually this makes it easier to reason about caching imo.

2. don't recurse into draw_vbo, collapse the GS launches into the draw. again
   this duplicates some code but makes it easier to reason about things and is
   probably faster. and makes part #1 feasible without piling on hacks (my
   original goal)

Alyssa Rosenzweig 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.

Alyssa Rosenzweig 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.

Alyssa Rosenzweig 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.
