i965/gen7: Handle atomic instructions from the VEC4 back-end.
This can deal with all the 15 32-bit untyped atomic operations the
hardware supports, but only INC and PREDEC are going to be exposed
through the API for now.
v2: Represent atomics as GLSL intrinsics. Add support for variably
indexed atomic counter arrays.
v3: Add comment on why we don't need to assign uniform storage for
atomic counters.
