intel/dump_gpu: Fix corner cases in PPGTT range calculations
For large buffers which span an entire l1 page table, we got the range
calculations wrong. In this case, we end up with an l1_start which is
the first byte represented by the given l1 table and an l1_end which is
the first byte after the range represented by the l1 table. Then
l2_start_index == L2_index(l2_end) due to roll-over. Instead, compute
lN_end using (1Ull << shift) - 1 so that lN_end is the last byte in the
range represented by the Nth level page table. When we do this, we
don't need the conditional expression anymore.

mesa: handle a bunch of formats in IMPLEMENTATION_COLOR_READ_*
Virgl could save a lot of work converting buffers in the host side
between formats if Mesa supported a bunch of other formats when reading
pixels.
This commit adds cases to handle specific formats so that the values
reported by the two calls match more closely the underlying native
formats.
In GLES is important that IMPLEMENTATION_COLOR_READ_* return the native
format and data type because the spec only allows reading with those,
besides GL_RGBA or GL_RGBA_INTEGER.
Additionally, because virgl currently doesn't implement such
conversions, this commit fixes several tests in
dEQP-GLES3.functional.fbo.color.clear.*, when using virgl in the guest
side.
The logic is based on knowledge that is shared with
_mesa_format_matches_format_and_type() but we cannot assert that the
results match as we don't have all the starting information at both
points. So leave the assert out and hope CI comes soon to save us all.

r600g: do not use "fast-clear" for small textures (v3)
Ported from radeonsi. Improves windowed glxgears ran as
vblank_mode=0 glxgears -info -geometry 0+0+512+512
from ≈2270 FPS to ≈2360 FPS. Tested with AMD TURKS.
v2: turned out glxgears ignores the option above, the correct way would
be "512x512+0+0". Now it can be seen 512x512 actually loses 30 FPS.
300×300 however wins around a hundred FPS, and to leave some room in
case results may differ for other cards I want not to nitpick in search
of an optimum but to simply leave 300×300 in the code.

glsl: do second pass of const propagation in loops
When handling loops in constant propagation, implement the "FINISHME"
comment like copy propagation: perform a first pass to find values
that can't be propagated, then perform a second pass with the ACP

Certain values are killed because the loop may run more than one

glsl: don't let an 'if' then-branch kill const propagation for else-branch
When handling 'if' in constant propagation, if a certain variable was
killed when processing the first branch of the 'if', then the second
would get any propagation from previous nodes. This is similar to the
change done for copy propagation code.
x = 1;
if (...) {
z = x; // This would turn into z = 1.
x = 22; // x gets killed.
} else {
w = x; // This would NOT turn into w = 1.
}
With the change, we let constant propagation happen independently in
the two branches and only then apply the killed values for the
subsequent code.
The new code use a single hash table for keeping the kills of both
branches (the branches only write to it), and it gets deleted after we
use -- instead of waiting for mem_ctx to collect it.
NIR deals well with constant propagation, so it already covered for
the missing ones that this patch fixes.

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

memory write instruction is emitted for an instruction group that writes up to all
four components.
