[Mesa-dev] Patches: R600: Improve load / store support for 8-bit and 16-bit types

[Aaron Watry]

It'll take me a while to attempt to parse everything that's going on
in these patches (and your resource descriptor types series that this
depends on), but I have sent it all through a piglit run on Evergreen
(Cedar).  Everything was latest Mesa/LLVM/libclc upstream code as of
today.

Baseline: 567/855 tests passed
Descriptors Series: 575/855 tests passed <-- Main differences here
were with some int3 load/store issues which were just exposed recently
and fixed by this series)
Descriptors + char/short load/store series: 880/1119 tests passed
(most of the additional tests and passes were char/short tests that no
longer crash out).

Specifically, I've double-checked the char/short/uchar/ushort built-in
functions, as well as the char/short arithmetic tests, and things are
looking good so far.  I'll try to test on Cayman/SI later.
