[Mesa-dev] [PATCH v2 72/78] i965/gs/gen6: Refactor ir_emit_vertex and ir_end_primitive for gen6

[Eduardo Lima Mitev]

From: Samuel Iglesias Gonsalvez <siglesias at igalia.com>

So the implementation is independent of GLSL IR and the visit methods of the
gen6 GS visitor. This way we will be able to reuse that implementation directly
from the NIR vec4 backend.
