Nouveau - Mar 2016 - [PATCH mesa 5/6] nouveau: codegen: Add support for OpenCL global memory buffers

tgsi_default_instruction_memory / tgsi_build_instruction_memory were
returning uninitialized memory for tgsi_instruction_memory.Texture and
tgsi_instruction_memory.Format. Note 0 means not set, and thus is a
correct default initializer for these.

Fixes: 3243b6fc97 ("tgsi: add Texture and Format to
tgsi_instruction_memory")

Use the dst temp variable which was used in the TGSI_FILE_OUTPUT
case everywhere. This makes the code somewhat easier to reads
and helps avoiding going over 80 chars with upcoming changes.

This also brings the dst handling more in line with the src
handling.

2.7.2

Make the store offset handling in CodeEmitterGK110::emitSTORE identical
to the one in CodeEmitterGK110::emitLOAD handling.

This is just a cleanup, it does not cause any functional changes.

FILE_MEMORY_GLOBAL is currently only used for buffer handling, as we
do not yet have (opencl) global memory support. Global memory support
actually requires some different handling during lowering, so rename
FILE_MEMORY_GLOBAL to FILE_MEMORY_BUFFER to reflect that the current
code is for buffer handling, this will allow the later (re-)addition
of FILE_MEMORY_GLOBAL for regular global memory.

2.7.2

Commit c3083c7082 ("nv50/ir: add support for BUFFER accesses")
disabled /
commented out some of the old resource handling code, but not all of it.

Effectively all of it is dead already, if we ever enter the old code
paths in handeLOAD / handleSTORE / handleATOM we will get an exception
due to trying to access the now always zero-sized resources vector.

Make non buffer / memory file accesses not being supported in these
functions more explicit and comment out a whole bunch of dead code.

Also remove the magic file-indexe defines from the old resource code
from include/pipe/p_shader_tokens.h as those are no longer used now
(which is a good thing).

This should be in a separate patch with "gallium:" as prefix even if 
nouveau is the only driver which somehow uses these constants.

Other than that, the patch looks fine.
And thanks to not remove this resource thing because this could help for 
arb_shader_image_load_store. :-)

I have the same comment as the previous patch, I think the cosmetic 
changes should not be here.

This approach leads to the emitters needing to know about both global and
buffer, even though at that point, they are identical. I was thinking that
in the lowering logic, buffer would just get rewritten as global (with the
offset added), thus not needing any change to the emitters. What do you
think about such an approach?
