[Mesa-dev] [PATCH 4/7] i965/blorp: Use R16_UNORM for Z32F surfaces.

Currently, all that matters is that we copy the correct number of bits,
so any format that has 32-bits of data will work fine.
Once BLORP begins handling format conversions, the sampler will need to
correctly interpret the data. We don't need a depth format, but we do
need the right number of components and data type (FLOAT).
For Z32F, this means using R32_FLOAT.
