This add paths to handle TGSI compute shaders and shader selection.
It also avoids emitting certain things on tgsi paths,
CBs, vertex buffers, config reg init (not required).

The atomic rat path has a bug in the ssbo path, refactor out the

This just changes how thread id loading is done, it makes
smaller shaders if we don't use thread id gprs.

On Cayman we don't use the append/consume counters (fglrx doesn't)
and they don't seem to work well with compute shaders.
This just uses GDS instead to do the atomic operations.
v1.1: remove unused line.
v2: use EOS on cayman, it appears to work.

This allow us to encapsulate the compiler and linkage requirements of
each driver in a reusable way. The result will be that each target that
needs a specific driver can simply add `driver_<name>` to its
dependencies line and the necessary libraries and compiler args will be
added. This will allow for a lot of code de-duplication between gallium
targets.

This just builds on the image support. Evergreen only has ssbo
for fragment and compute no other stages.
v2: handle images and ssbo in the same shader properly (Ilia)
v3: fix RESQ on buffers,
fix missing atom emit
fix first element offset
use R32 format
write separate buffer rat store path.

This fixes hangs on cayman with
tests/spec/arb_tessellation_shader/execution/trivial-tess-gs_no-gs-inputs.shader_test
This has a single if/else in it, and when this peephole activated,
it would set the jump target to NULL if there was no instruction
after the final POP. This adds a NOP if we get a jump in this case,
and seems to fix the hangs, so we have a valid target for the ELSE
instruction to go to, instead of 0 (which causes infinite loops).
v2: update last_cf correctly. (I had some other patches hide this)

So far on pre-cayman chipsets the CF instructions CF_OP_LOOP_END,
CF_OP_CALL_FS, CF_OP_POP, and CF_OP_GDS an extra CF_NOP instruction
was added to add the EOP flag, even though this is not actually
needed, because all these instrutions support the EOP flag.
This patch removes the fixup code, adds setting the EOP flag for the
according instructions as well as others like CF_OP_TEX and CF_OP_VTX,
and adds writing out EOP for this type of instruction in the disassembler.
This also fixes a bug where shaders were created that didn't actually have
the EOP flag set in the last CF instruction, which might have resulted
in GPU lockups.
