This was a bug from the MSAA enabling. Tests for surfaces with
nr_samples==1 instead of 0 (generally GL renderbuffers) would incorrectly
fail out.
Fixes the ARB_framebuffer_sRGB piglit tests other than srgb_conformance.

I had made the previous blit fix non-MSAA only because I was thinking
about how the hardware infers stride from the RENDERING_CONFIG packet.
However, I'm also inferring the stride for both MSAA src and dst in
vc4_render_cl.c from the width argument in the ioctl.
Fixes 15 EXT_framebuffer_multisample piglit tests.

Previously, we were relying on has_matching_typed_format returning true for
MESA_FORMAT_NONE which, in turn, relied on _mesa_get_format_bytes returning
1 for MESA_FORMAT_NONE. When we switch to ISL, this behaviour will no
longer be something we can rely on.

Starting with Skylake, the display engine is capable of scanning out from
Y-tiled buffers. As such, we can and should use Y-tiling for better efficiency.
This also has the added benefit of being able to fast clear the winsys buffer.
Note that the buffer allocation done for mipmaps will already never allocate an
X-tiled buffer for GEN9.
This has an almost universal positive impact on benchmarks, some improving by as
much as 20%.

Screwed up since 0753b135f6.
(Only an issue with different min/mag filters, and then only in some cases,
which is probably why it went unnoticed for quite a while.
The effect should have simply been nearest mip filter instead of linear, iff
min was nearest, mag was linear, and all pixels hit the mignifying path.)

In commit cda886a485, Neil made us stop
advertising RGBX formats on Gen9+, as the hardware apparently no longer
has working fast clear support for those formats. Instead, we just
fall back to RGBA formats, and use SCS to override alpha to 1.0.
This is fine, but had one unintended side effect: it made us fall back
to slow clears when the color mask disables alpha. Normally, we ignore
the color mask for non-existent channels. This includes alpha for XRGB
formats as writing garbage to the X channel is harmless. But, now that
we use RGBA, we think there's a real alpha channel, and can't do the
optimization.
To hack around this, check if _BaseFormat is GL_RGB and ignore alpha.
Improves WebGL Aquarium performance on Skylake GT3e by about 50%
by letting it use repclears instead of slow clears.

We do this in two steps: first we clip the dst rect and adjust the src
rect accordingly. Then we do it the other way around. In both passes
the adjustment part involves multiplying by a scale factor that can lead
to a small precision loss. This is breaking a few dEQP tests.
Specifically, the problem happens when we need to clip the same coordinate
twice. For example, if srcX0 and dstX0 need both to be clipped we want to
avoid the situation where we clip srcX0 first, then adjust dstX0 accordingly
but then we realize that the resulting dstX0 still needs to be clipped, so
we clip dstX0 and adjust srcX0 again. Each of these two passes can lead
to precission loss. What we want to do here is detect the rect that leads
to the largest clip (accounting for the scale factor involved), clip that
rect and adjust the other one. With this we ensure that the adjusted
coordinate does not need to be clipped again and we can skip a second pass,
improving precision.

dEQP-GLES3.functional.fbo.blit.rect.out_of_bounds_reverse_src_x_nearest
