[Mesa-dev] Mesa (master): mesa/formats: Add layout and swizzle information

[Jason Ekstrand]

Michael,
With the two patches I just sent to the list, the generated format_info
structure is now binary-identical to the original structure commited to git
with the following two exceptions: The string name parameter for
MESA_FORMAT_R9G9B9E5_FLOAT was updated from "MESA_FORMAT_RGB9_E5" to
"MESA_FORMAT_R9G9B9E5_FLOAT".  The LATC formats now report 8 bits of
precision instead of 4;  This makes the LATC formats match the RGTC formats
which use exactly the same compression just interpreted differently.

I'm really confused about where the bug is coming from.  That said, I'm
going to run some llvmpipe tests to see if I can reproduce.
