We don't support stencil-exports yet, and even when we will, we might
not support it on all hardware. So we really need an alternative plan
here, even when render_condition_enable is true.
Fixing this properly is much more involved, and depends on reworking
render-condition along the lines that we do in !7746 to support pausing
and resuming properly first. So let's do the minimal thing, which is to
allow this to work in cases where no render-condition is active.

NTT doesn't handle uniforms, and requires them to have been lowered to
UBOs. But for drivers that don't set
nir_shader_compiler_options::lower_uniforms_to_ubo to true, this won't
have happened yet. Neither Zink nor V3D sets this option, and in the
case of Zink this isn't trivial to change.
So let's lower uniforms to UBOs in this case in NTT instead.

There is a path to blit stencil buffers reinterpreting the stencil data
as an RGBA8888 or R8 float texture.
This works fine except for the case when the stencil buffer is
multisampled, and the blit operation needs to resolve it: an average of
the samples is done, which is incorrect, as only one sample must be
used.
This can be observed n the piglit test
`ext_framebuffer_multisample-unaligned-blit 2 stencil downsample -auto
-fbo`, specifically in the triangles border.
To avoid this averaging, let's reinterpret the stencil data as RGBA8888
or R8 uint texture.

LLVM expects that exec != 0 when entering loops and generates this code
that becomes an infinite loop if exec == 0:
BB5_1:
vcc_lo = (inverted terminating condition)
s_and_b32 vcc_lo, exec_lo, vcc_lo
s_cbranch_vccnz BB5_3 // jump if vcc != 0 (break statement)
// ... loop body ...
s_branch BB5_1
BB5_3:
For non-monolithic VS before TCS, VS before GS, and TES before GS,
we set exec = (thread enabledmask), which sets 0 for HS-only and GS-only
waves, causing the infinite loop condition above.
Fix it as follows:
- set exec = ~0 at the beginning
- wrap the whole shader (LS and ES) in a conditional block, so that HS-only
and GS-only waves jump over it and never enter such a loop
The TES before GS hang can be reproduced by gfxbench:

Stencil texture sampling (such as what we have to do for BlitFramebuffer)
is broken with UBWC enabled. We can't just take the
fd_resource_uncompress() path, because that's a blit just like
BlitFramebuffer.
Fixes failure in dEQP-GLES3.functional.fbo.msaa.2_samples.stencil_index8,
but also the uncaught rendering fails of 4_samples.stencil_index8 and
depth24_stencil8.
Prior to "911ce374caf0 freedreno/a6xx: Fix MSAA clear" we would usually
pass and sometimes flake fail on this test occasionally, thus it being
listed as a flake (though the rendering was actually broken). Since that
commit, though, we consistently fail on a pixel of the broken rendering,
and thus this was brought to my attention by the #freedreno-ci channel
spam.
Rob took a look at the performance impact of this, and the worst was maybe
up to .5% fps hit on trex.

then the gallium draw module triggered the non-LLVM TGSI fallback path
that hit NTT).

anyway.

There's not really a reason to directly map textures. Doing so
requires the texture to be allocated in system RAM instead of
video RAM, which means all GPU access to it would be needlessly slow.
Notably, the one texture type that was allocated this way is the
display target texture for the software driver path. Instead, use
pipe_transfer_map to be able to copy the texture to system RAM.
