nir: Unset metadata debug bit if no progress made
NIR metadata validation verifies that the debug bit was unset (by a call
to nir_metadata_preserve) if a NIR optimization pass made progress on
the shader. With the expectation that the NIR shader consists of only a
single main function, it has been safe to call nir_metadata_preserve()
iff progress was made.
However, most optimization passes calculate progress per-function and
then return the union of those calculations. In the case that an
optimization pass makes progress only on a subset of the functions in
the shader metadata validation will detect the debug bit is still set on
any unchanged functions resulting in a failed assertion.
This patch offers a quick solution (short of a larger scale refactoring
which I do not wish to undertake as part of this series) that simply
unsets the debug bit on unchanged functions.

radeonsi: Fix use of 1- or 2- component GL_DOUBLE vbo's.
With Mesa 18.1, commit
be973ed21f6e, si_llvm_load_input_vs()
changed the number of source 32-bit wide dword components
used for fetching vertex attributes into the vertex shader
from a constant 4 to a variable num_channels number, depending
on input data format, with some special case handling for
input data formats like 64-Bit doubles.
In the case of a GL_DOUBLE input data format with one
or two components though, e.g, submitted via ...
a) glTexCoordPointer(1, GL_DOUBLE, 0, buffer);
b) glTexCoordPointer(2, GL_DOUBLE, 0, buffer);
... the input format would be SI_FIX_FETCH_RG_64_FLOAT,
but no special case handling was implemented for that
case, so in the default path the number of 32-bit
dwords would be set to the number of float input components
derived from info->input_usage_mask. This ends with corrupted
input to the vertex shader, because fetching a 64-bit double
from the vbo requires fetching two 32-bit dwords instead of 1,
and fetching a two double input requires 4 dword fetches
instead of 2, so in these cases the vertex shader receives
incomplete/truncated input data:
a) float v = gl_MultiTexCoord0.x; -> v.x is corrupted.
b) vec2 v = gl_MultiTexCoord0.xy; -> v.x is assigned
correctly, but v.y is corrupted.
This happens with the standard TGSI IR compiled shaders.
Under NIR with R600_DEBUG=nir, we got correct behavior
because the current radeonsi nir code always assigns
info->input_usage_mask = TGSI_WRITEMASK_XYZW, thereby
always fetches 4 dwords regardless of what the shader
actually needs.
Fix this by properly assigning 2 or 4 dword fetches for
one or two component GL_DOUBLE input.

llvmpipe: Always return some fence in flush (v2)
If there is no last fence, due to no rendering happening yet, just
create a new signaled fence and return it, to match the expectations of
the EGL sync fence API.
Fixes random "Could not create sync fence 0x3003" assertion failures from
Skia on Android, coming from the following code:
https://android.googlesource.com/platform/frameworks/base/+/master/libs/hwui/pipeline/skia/SkiaOpenGLPipeline.cpp#427
Reproducible especially with thread count >= 4.
One could make the driver always keep the reference to the last fence,
but:
- the driver seems to explicitly destroy the fence whenever a rendering
pass completes and changing that would require a significant functional
change to the code. (Specifically, in lp_scene_end_rasterization().)
- it still wouldn't solve the problem of an EGL sync fence being created
and waited on without any rendering happening at all, which is
also likely to happen with Android code pointed to in the commit.
Therefore, the simple approach of always creating a fence is taken,
similarly to other drivers, such as radeonsi.
Tested with piglit llvmpipe suite with no regressions and following
tests fixed:
egl_khr_fence_sync
conformance
eglclientwaitsynckhr_flag_sync_flush
eglclientwaitsynckhr_nonzero_timeout
eglclientwaitsynckhr_zero_timeout

anv: flush fast clear colors into compressed surfaces
In the following scenario :

2. Create image view format R8G8B8A8_SRGB
3. Clear the view through a sub pass to a particular color
4. Barrier on the image to from color attachment to source transfer
5. Copy the image into a linear buffer to check the content
The step 4 resolving the clear color is unaware of the SRGB format of
the view, because the blorp resolve operations operate on images the
color associated with the resolve will not operate on SRGB format but
UNORM. Leading to the wrong color being written into surfaces.
This change forces a clear color resolve at the end of the render pass
so following resolves won't have to deal with the clear color with a
format that doesn't match the image's format.
