6abbef04b0 nvk/nak: Translate our new FS flags from NAK to nvk_shader

Put the stuff in nak_shader_info in nak.h into a union so we can have
other stage info exported as well.  Then plumb local_size and smem_size
through ShaderInfo like we do for a bunch of the FS things.  While we're
shuffling things around, pull nak_shader_info::cs into a union.

9eeda9dd6d nak: Rework FS outputs again 
This time we map them to a consistent output address space like we do
for all other I/O and system values and do the remap in nak_from_nir.
This lets us know very precise usage information and more robustly build
the OMask in the shader header.  We also handle location_frac now.

ecf5c4c13b nak: Properly handle OpFSOut in RA and liveness 
That one's a bit magic because it exists to ensure that each output GPR
ends up in the right register at the end of the shader.  We tried to
handle it as a simple lowering before but it's easier and safer to
handle it directly in RA and liveness.

a07aa29f61 nak: Re-work Instr::get_latency() 
We re-order and re-arrange the whole thing by instruction type.  Also,
instead of returning an Option<u32>, have a has_fixed_latench() method
to check the instruction and then get_dst_latench() to get the latency
from instruction launch to the given destination index being available.
This lets us handle predicates properly which have a different number of
cycles for some reason.  Oh, it's now just as correct as the estimates
in nv50_ir_target_gm107.cpp.

2288b33a48 nak: Rework the barrier insert pass 
This is mostly a refactor but it does tuck in a three functional
changes:

 1. We no lonter insert read barriers for sources that we immediately
    overwrite in the instruction.

 2. We track read and write barriers separately so we don't wait for
    read-after-read hazards but do for write-after-read.

 3. Wait on all barriers in branch instructions
