The commit is wrong for several reasons. One of them is when we grab
a new buffer, we should update all the states it is bound in,
including all parallel contexts. I don't think this is even doable.
The correct solution would be upload data via a temporary buffer and
do resource_copy_region to the original one.

mesa: Add fall-back formats for unsupported snorm formats
This is always the way with real hardware and desktop OpenGL. Some
hardware can't do some formats natively. The alpha-only, luminance,
and intensity formats are usually the most problematic. Some sized
formats can also be problematic. This patch provides fall-back
formats for those that are not natively supported.
At some point it would be interesting to try providing
device-independent conversions using EXT_texture_swizzle. The drivers
that support EXT_texture_swizzle could, for example, see
GL_LUMINANCE16_SNORM as MESA_FORMAT_SIGNED_R16 with a { r, r, r, 1 }
swizzle. Care would need to be taken to prevent issues with using
those textures for FBO rendering.
This is the rest of the fix for glean's pixelFormats test on i965.

i965: Add the missing supportable EXT_texture_snorm formats
This class of hardware can natively sample all of the snorm surface
formats that DX10 requires, but it can't do some of the legacy GL
formats. In particular, all of the alpha, luminance, and intensity
formats are unsupported.
This partially fixes the breakage in glean's pixelFormats test since
GL_EXT_texture_snorm support was added to Mesa.

We use this format to represent the accum buffer. No snorm texture
