i965, anv: Use NIR FragCoord re-center and y-transform passes.
This handles gl_FragCoord transformations and other window system vs.
user FBO coordinate system flipping by multiplying/adding uniform
values, rather than recompiles.
This is much better because we have no decent way to guess whether
the application is going to use a shader with the window system FBO
or a user FBO, much less the drawable height. This led to a lot of
recompiles in many applications.
