If the scissor test is enabled, the intersection of both is used.
The guard band will disable clipping, so we have to clip per-pixel.

This is in preparation of raising the number of exposed sampler views to 32
bits, which will raise the total number of sampler views to 33 for the
polygon stipple texture. That texture should never be compressed (and it's
certainly not a depth texture), but this approach seems cleaner to me than
special-casing the last slot in all affected code paths.

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).

V4:

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.
