freedreno/ir3: fix # of registers

The instruction encoding allows for more registers, but at least on

add REVIEWERS and get_reviewer.pl script

Copied from linux kernel (where it is called MAINTAINERS and
get_maintainer.pl), with minimal changes to script (to recognize
mesa src tree rather than linux kernel src tree, and to avoid
accidentaly CC'ing Linus Torvalds on mesa patches), and slimmed
down MAINTAINER file syntax to recognize that we don't really have
subsystem "maintainers" in the same sense as the linux kernel (ie. no
different mailing lists and git trees per subsystem).

The main point is to automate slapping on the correct CC's for patches
via git's --cc-cmd feature, more than anything else.

I didn't attempt to fully populate the REVIEWERS file, by a long shot.
This is an opt-in system and anyone else can add their own entries.

To utilize:

  git send-email --cc-cmd ./scripts/get_reviewer.pl ...

or to configure it to be the default:

  git config sendemail.cccmd ./scripts/get_reviewer.pl

nouveau/video: properly detect the decoder class for availability checks

tell it how many threads to dispatch and manually configure the channel

run it in either SIMD4x2 or SIMD8 mode.

Treating it as SIMD8 means that shaders with 8 or fewer output vertices
(which is overwhemingly the common case) can be handled by a single
thread.  This has several intriguing properties:

- Accessing input arrays with gl_InvocationID as the index is a simple
  SIMD8 URB read with g1 as the header.  No indirect addressing required.
- Barriers are no-ops.

nv50,nvc0: re-bind old compute state after reading MP perf counters

This might be useful to avoid breaking the current compute state when
monitoring MP perf counters because we use a compute kernel to read out
those counters. This has been initially suggested by Ilia Mirkin.

nir: make lower_clamp_color pass work after lower i/o

Kinda important to work with tgsi_to_nir, which generates nir which
already has i/o lowered.

vc4: Use NIR lowering for sRGB decode.

This should get us the same decode code generated, but with a lot less
custom code in the driver.

vc4: Just use NIR lowering for texture projection.

This means doing Newton-Raphson on the RCP, but it's probably actually a
good thing to be accurate on.

vc4: Scalarize phi nodes as well.

This makes fewer programs with loops assertion fail, replacing them with
the rendering failure warning.

vc4: Add whitespace after each program stage dump.

In particular it's been hard to find the point where we switch from
dumping pre-optimization QIR and post-optimization QIR.

vc4: Remove the CSE pass.

It's not doing anything according to shader-db now that we're using NIR.
It would have had to be reworked significantly anyway, to handle control
flow.

vc4: Emit only one FRAG_Z or FRAG_W QIR opcode.

We were generating piles of FRAG_W for interpolation, only to CSE them
away immediately.  Since this is the only thing that CSE is doing for us
any more, just avoid making the CSE work necessary.

vc4: Use the NIR cubemap normalization instead of our own.

This is one of two uses of the current QIR CSE pass according to
shader-db.  The NIR pass means that we'll end up doing Newton-Raphson on
our RCP, which we weren't doing before, but that's probably actually a
good thing.

vc4: Drop the support for DCE of texture instructions.

Now that we're using NIR for our optimization, there's no need for this
tricky code.

radeonsi: fix PIPE_FORMAT_R11G11B10_FLOAT handling
