Re-allocate rather than re-use. Originally we had an unnecessarily
complex design to avoid re-allocating cmdstream buffers. But now that
support for "growable" cmdstream buffers has been in place for a couple
years, I guess we can care a bit less about the extra overhead on older
kernels.
But making the batches one-shot removes a class of potential race
conditions vs the flush_queue.

Instead of the reading batch setting a dependency on the writing batch,
simply flush the writing batch immediately. This avoids situations
where we have to flush the context's current batch later.

pipe_framebuffer_state can have samples=0 in various cases, which is

It is possible for a batch to be freed under our feet when flushing, so
it is best to hold a reference to all of them up-front.

The current code is buggy: if there are only 12 dwords left in cbuf,
we emit a zero data length command which will be rejected by virglrenderer.

The current spill code checks in each instruction of an instruction group whether
spilling is needed and if so, it adds spilling for each component as a seperate
instruction and it allocates a new temporary for each component and since it takes
the write mask from the TGSI representation, all components might be written
each time and as a result already written components might be overwritten with
garbage like:
...
y: MOV R9.y, [0x42140000 37].x
t: MOV R8.x, [0x42040000 33].y
...
MEM_SCRATCH WRITE_IND_ACK 0 R9.xy__, @R4.x ES:3
MEM_SCRATCH WRITE_IND_ACK 0 R8.xy__, @R4.x ES:3
...
To resolve this isse accumulate spills to the same memory location so that only one
memory write instruction is emitted for an instruction group that writes up to all
four components.

For V3D, the HW will interpolate slightly differently along the shared
edge of the trifan. The conformance tests manage to catch this in the
nearest_consistency_* group. To get interpolation to match, we need the
last vertex of the triangle to be shared.
I first tried implementing draw_rectangle to do triangles instead, but
that was quite a bit (147 lines) of code duplication from u_blitter, and
this seems much simpler and less likely to break as u_blitter changes.

The vtest protocol is pretty simple but also pretty dumb, and
the v1 caps query was fixed size, with no nice way to expand it,
however the server also ignores any command it doesn't understand.
So we can query v2 caps by sending a v2 followed by a v1, if the
v2 is ignored we know it's an old vtest server, and the we get
a v2 answer then we can just read the v1 answer and discard it.

fold_assoc() called from fold_alu_op3() can lower the number of src to 2,
which then leads to an invalid access to n.src[2]->gvalue().
This didn't seem to have caused much harm in the past, but on Fedora 28
it will crash (presumably because -D_GLIBCXX_ASSERTIONS is used, although
with libstdc++ 4.8.5 this didn't do anything, -D_GLIBCXX_DEBUG was
needed to show the issue).
An alternative fix would be to instead call fold_alu_op2() from within
fold_assoc() when the number of src is reduced and return always TRUE
from fold_assoc() in this case, with the only actual difference being
the return value from fold_alu_op3() then. I'm not sure what the return
value actually should be in this case (or whether it even can make a
difference).

phi instructions don't have the same results by simply having the same sources.
They need to be inside the same BasicBlock or share an equal condition
resulting into a path through the shader selecting equal sources as well.
short example:
cond = ...;
const0 = 0;
const1 = 1;
if (cond) {
ssa_1 = const0;
} else {
ssa_2 = const1;
}
ssa_3 = phi ssa_1 ssa_2;
if (!cond) {
ssa_4 = const0;
} else {
ssa_5 = const1;
}
ssa_6 = phi ssa_4 ssa_5;
allthough both phis actually have sources with equal results, merging them
would be wrong due to having a different condition selecting which source to
take.
For now we also stick an assert into GlobalCSE, because it should never end up
having to merge phi instructions.

Cleans up the CL of fbo-drawbuffers2-blend a bit. We could do better on
more complicated cases by noticing if multiple RTs have the same blend
state and emitting them in a single packet.
Commit f69bc797e1 did the following:
- if format.layout in ('bptc', 'astc'):
+ if format.layout in ('astc'):
The intention was to go from matching either 'bptc' or 'astc' to
matching only 'astc'.
But the new code doesn't respect this intention any more, because in
Python `('astc')` is not a tuple containing a string, it is just the
string. (the parentheses are simply ignored)
That means we now match any substring of 'astc', for example 'a'.
This commit fixes the test to respect the original intention.
