When alphaToCoverage is enabled, we should always write the alpha
channel of MRT0 if it's unused. This now matches RadeonSI.
This fixes the new CTS:

Basically, this extension allows applications to use custom
sample locations. It doesn't support variable sample locations
during subpass. Note that we don't have to upload the user
sample locations because the spec doesn't allow this.
The extension is currently disabled because the driver needs to
support variable sample locations during layout transitions. The
depth decompress needs to know them and that's a bit invasive.

We already use GFX9 and I don't want us to have confusing naming
in the driver. GFXn naming is better from the driver perspective,
because it's the real version of the gfx portion of the hw. Also,
CIK means Bonaire-Kaveri-Kabini, it doesn't mean CI.
It shouldn't confuse our SDMA, UVD, VCE etc. code much. Those have
nothing to do with GFXn and they have their own version numbers.
We need to know the number of rectangles.

This patch does it as late as possible so the potential extra

The per stage time is only an approximation due to linking and

It's common in some applications to bind a new graphics pipeline without
ending up changing any context registers.
This has a pipline have two command buffers: one for setting context
registers and one for everything else. The context register command buffer
is only emitted if it differs from the previous pipeline's.
v2: ensure late scissor emission is done when radv_emit_rbplus_state() is
called
v2: make use of cmd_buffer->state.workaround_scissor_bug
v3: rename "workaround_scissor_bug" to
"context_roll_without_scissor_emitted"

Looking at -pro we need to enable it for pipelines with just a

The pass detects that the temporary array created by DXVK for
storing TCS inputs is a copy of the input arrays and allows
us to avoid copying all of the input data and then indirecting
on it with if-ladders, instead we just do indirect indexing.
