Some games are sloppy.. perhaps because it is defined behavior for DX or
perhaps because nv blob driver defaults things to zero.
So add driconf param to force uninitialized variables to default to zero.

In exclusive mode, any fragment inside any of the specified rectangles

The goal is to allow the pipe driver to request something other than
TGSI, but detect whether what is getting is TGSI vs what it requested.
The pipe drivers will always have to support TGSI (and convert that into
whatever it is that they prefer), but in some cases we should be able to
skip the TGSI intermediate step (such as glsl->nir vs glsl->tgsi->nir).
I think pipe_compute_state should get similar treatment. Currently,
afaict, it has one user and one consumer, which has allowed it to be
sloppy wrt. supporting alternative IR's.

The previous value of 18 was motivated by having drivers that want to expose
16 samplers but also use some additional samplers for internal use. Raising
the value even higher isn't going to hurt that case.
On the other hand, some drivers actually use PIPE_MAX_SAMPLERS as the number
of samplers they expose externally, so raising this number above 32 is fragile
(because several places in the code use bitfields, and tracking down and
widening all of them is prone to miss some case).

Here we store the number of samples and layers directly in the

util_framebuffer_get_num_samples() to their canonical form.
V3:
'git stash pop' the typo fix of 'cbufs' which should be

pointing this out yet again.
V4:
Squash in the following patch:
'gallium/util: Ensure util_framebuffer_get_num_samples() is valid'
Upon context creation, internal driver structures are malloc()'ed
and memset() to zero them. This results in a invalid number of
samples 'by default'. Handle this in the simplest way to avoid
elaborate and probably equally sub-optimial solutions.

Radeonsi needs to know which shader stage will execute after a shader
in order to make the best decision about which shader variant to compile
first.
This is only set for VS and TES, because we don't need it elsewhere.
VS has 3 variants:
- next shader is FS
- next shader is GS
- next shader is TCS
TES has 2 variants:
- next shader is FS
- next shader is GS
Currently, radeonsi always assumes the next shader is FS, which is suboptimal,
since st/mesa always knows which shader is next if the GLSL program is not
a "separate shader".
By default, ureg always sets "next shader is FS".
