From: Rob Clark <robcl...@freedesktop.org>
Some hardware needs to know the sampler type. Update the blit related
shaders to include SVIEW decl.

Possibly I should have refactored the existing code to pass around a
return_type rather than doing the is_uint/is_sint thing everywhere.
And this does kind of ignore UNORM/SNORM.. although I'm not really
sure that we need shader variants for UNORM/SNORM (we don't have this
information in GLSL IR or NIR IR, and I don't know any hw that doesn't
just treat those as FLOAT in the shader compiler). Anyways, sending
it out as-is for comments.
