tgsi: Add support for global / private / input MEMORY

Browse Source 
Extend the MEMORY file support to differentiate between global, private
and shared memory, as well as "input" memory.

"MEMORY[x], INPUT" is intended to access OpenCL kernel parameters, a
special memory type is added for this, since the actual storage of these
(e.g. UBO-s) may differ per implementation. The uploading of kernel
parameters is handled by launch_grid, "MEMORY[x], INPUT" allows drivers
to use an access mechanism for parameter reads which matches with the
upload method.
