d94584c5a6 panfrost: Always use SOFTWARE for pure formats 
Otherwise we end up implicitly converting ints to floating point.
Likewise for floats which again have strange interactions.

a3952e927e panfrost: Use f2fmp for framebuffer lowering conversions 
This allows the conversion to be removed when the output is needed as
f32 anyway, for example for highp framebuffer fetch.

v2: Also change operations such as i2i16 to i2imp (Alyssa).

d16d136734 panfrost: Stop keying on rt format when using native loads 
Native loads are the same for any format, so we can use the same
shader variant for all framebuffer formats with a native load.

1e1eee992e pan/mdg: Do the pan_lower_framebuffer pass later 
The pass is useful for EXT_shader_framebuffer_fetch, not just blend
shaders, so we should do it with the other lowering passes in
midgard_compile_shader_nir.

afc18c62d7 panfrost: Passthrough NATIVE loads/stores 
Now that we handle load_output directly, this works for e.g. RGB565 on
Midgard.
