nir: add a pass to clamp gl_PointSize to a range
The OpenGL and OpenGL ES specs require that implementations clamp the
value of gl_PointSize to an implementation-depedent range. This pass
is useful for any GPU hardware that doesn't do this automatically
for either one or both sides of the range, such as V3D.
v2:
- Turn into a generic NIR pass (Eric).
- Make the pass work before lower I/O so we can use the deref variable
to inspect if we are writing to gl_PointSize (Eric).
- Make the pass take the range to clamp as parameter and allow it
to clamp to both sides of the range or just one side.
- Make the pass report progress.
v3:
- Fix copyright header (Eric)
- use fmin/fmax instead of bcsel to clamp (Eric)
