The branch instruction has 6 bits per register operand which allows it
to specify a component in the register.
Fix codegen so that it outputs the right component, otherwise it always
outputs the x component.

This is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

st_extensions.c sets const->MaxImageSamples (GL_MAX_IMAGE_SAMPLES) by
looping over [16, 15, .. 1x] MSAA modes, and RGBA/BGRA/ARGB/ABGR 8888
color formats, calling pipe->is_format_supported() for each, with
the usage set to PIPE_BIND_SHADER_IMAGE. If any are supported, it
selects that number of samples.
We were checking if sample_count <= 1, which meant that we were getting
a value of 1x MSAA, rather than the expected 0x (feature doesn't exist).
But, only on Icelake because Gen11 adds support for typed read messages
for R8G8B8A8_UNORM. The lack of typed read messages for these formats
was tricking the check on Gen9 to say no correctly. This caused some
Icelake conformance failures, because we don't implement this feature.
Just check for sample_count == 0 instead.
Glamor in xorg-server 1.20 cannot expose 16bpp pixmaps when running in
the usual 24bpp mode. This meant our 565 pbuffer configs would
ultimately fail to create a backing pixmap, leading to crashes.
To hack around this, make a 16bpp pixmap and try and export it.
If it works, expose the configs. Otherwise, just skip them.
This also disables them on DRI2. These configs were only added to pass
conformance requirements, and I doubt anybody cares about testing out
565 pbuffer visuals on DRI2-only drivers.

In commit dacb11a585, Eric found the first
matching 565 pbuffer config, and stopped. Our double-buffered configs
come first in the list, so we added that, making a pbuffer-only config
that claimed to be double buffered. This doesn't make sense, since
pixmaps/pbuffers are fundamentally not double buffered.
When using that config, every call to eglCreatePbufferSurface would fail
with EGL_BAD_MATCH. The call chain looks like this:
- eglCreatePbufferSurface
- dri3_create_pbuffer_surface
- dri3_create_surface
- dri2_get_dri_config
which eventually does:
const bool double_buffer = surface_type == EGL_WINDOW_BIT;
and then fails to find a matching config, because it ends up looking
for a single-buffered config - and there aren't any.
To fix this, make the 565 pbuffer config single-buffered. This fixes
at least 51 dEQP-EGL.* tests.

Normally, we haven't worried too much about stack sizes as Linux tends
to be fairly friendly towards large stacks. However, when running DXVK
apps under wine, we're suddenly subject to Windows' more stringent stack
limitations and can run out of space more easily. In particular, some
of the shaders in Elite Dangerous: Horizons have quite a few registers
and the arrays in split_virtual_grfs are large enough to blow a 1 MiB
stack leading to crashes during shader compilation.
