Probably for some time now the generics are moved from index 0-31
to 9-40, and this doesn't fit the masks we were using, so use
64 bit masks.
Apparently this only triggered an assert and didn't lead to further
failures when the assertion was not enabled so that the CTS didin't
catch this.
We could also use 32 bit masks and shift the index by 9, but if
this would get us into trouble we ever decide to switch the
PIPE_CAP_TGSI_TEXCOORD in mesa/virgl.
Fixes a number of piglits from the glsl-1.10 set that otherwise trigger
an assertion.

When emitting GLSL for atomic_uint variables, use the binding location

vkr_ring_read_buffer now supports reading from a ring buffer that is on
top of iov. It is overly complex though.
For further optimization and simplication, we should consider requiring
a logically contiguous virgl_resource. Possible options are requiring a
physically contiguous guest memory (this can have other use cases) or
requiring a host VkDeviceMemory (already doable, but meh).
We also use the chance to replace size_t by uint32_t in
vkr_ring_read_buffer. No functional difference.

VkDrmFormatModifierPropertiesListEXT::drmFormatModifierCount may be used
uninitialized. It is a codegen bug but a proper fix breaks the
protocol. Until we are ready to finalize the protocol, let's work
around it.
It works so far because Mesa calls the function twice in a row. In the
first call, pDrmFormatModifierProperties is NULL and the uninitialized
value is not used. Instead, it is initialized by the host driver.
In the second call, because of how the temp pool works, the memory gets
reused and the "uninitialized value" is already initialized. Thanks
goes to Yiwei for figuring this out.

the indexing behavior for shadow samplers in some related code cleaning.
shadow_samp_*_locs arrays are currently indexed according to the bit
position of a sampler in samplers_used_mask and shadow_samp_mask, so
sampler_index must be incremented for each sampler, not just for each
shadow sampler.
