mesa: Add a new function for getting the nonconst sampler array index
If the array index is not a constant expression, the existing support
will assume a zero offset (giving us the sampler index of the base of
the array).
For dynamically uniform indexing of sampler arrays, we need both that
and the indexing expression.

vc4: Clean up the tile alloc buffer size.
This prevents some simulator assertion failures, but it does mean (since
I've dropped the "* 16" padding) that on real hardware you need a kernel
that does overflow memory management (currently, "drm/vc4: Add support for
binner overflow memory allocation." in my kernel tree).

vc4: Use GEM under simulation even for non-winsys BOs.
In addition to reducing sim-specific code, it also avoids our local handle
allocation conflicting with the host GEM's handle numbering, which was
causing vc4_gem_hindex() to not distinguish between winsys BOs and the
same-numbered non-winsys bo.
