gallium/tgsi: start adding hw atomics (v3.2)
This adds support for a hw atomic counters to TGSI.
A new register file for storing atomic counters is added,
along with a new atomic counter semantic, along with docs
for both.
v2: drop semantic, move hw counter to backend,
Ilia pointed out SSO would have busted my plan, and he
was right.
v3: drop BUFFER decls. (Marek)
v3.1: minor fixups for whitespace, set ureg error
if we overflow the hw atomic limits. (nha)
v3.2: fix some docs inconsistencies (Ilia)
