8417f4a8eb nir: move nir_lower_drawpixels() to the state tracker 
This is gl specific and a following fix will add more gl specific
params so here we move it to the st to avoid filling nir.h with
more junk.

The highest possible values that can be represented with

In order to ensure 1023 maps to 65535 in the Sx10 case
we thus need to multiply by 65535 / 1023 ~= 64.06158
instead of 64.

e78bd88a06 nir/opt_offsets: add callback to set need_nuw per intrinsic
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
Wether need_nuw is used is currently decided in two different ways:
- globally through the allow_offset_wrap option;
- per intrinsic but hard-coded in opt_offsets.

Make this more flexible by creating a callback that is called per
intrinsic. This will allow backends to decide, on a per-intrinsic basis,
whether need_nuw is needed.

Note that the main use case for ir3 is to add support for opt_offsets
for global memory accesses. Other intrinsics don't need need_nuw but
global memory accesses do.

26e32417b9 nir: Add an option to make lower_phis_to_regs_block() less clever 
Right now it tries to place reg_write instructions as far up the
predecessor chain as possible.  This is useful for a bunch of the passes
that call it since it ensures they don't get placed in dead blocks or in
single successors and things like that.  But it screws up NAK's control
flow lowering so we need the option to turn it off and make the pass
place the reg_write instructions in the most obvious place possible.

Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
The previous algorithm just looked at the dominator's loop header.
However, if you have multiple consecutive loops like:

    function_impl {
        loop {
            // Stuff
        }
        loop {
            // Other stuff
        }
    }

then it will look like the second loop is contained in the first loop
because the first loop's header dominates the second loop.  This isn't
actually what we want.  Instead, we want a node N to be considered part
of a loop with header H if H dominates N and H is reachable from N.
