Since we're using nir_lower_outputs_to_temporaries to shadow all our
outputs, it's impossible to actually get an indirect store. The code we
had to "handle" this was pretty bogus as it created a register with a
reladdr and then stuffed it in a fixed varying slot without so much as a
MOV. Not only does this not do the MOV, it also puts the indirect on the
wrong side of the transaction. Let's just delete the broken dead code.

It's not really buying us anything at this point. It's just a way of
remapping one offset namespace onto another. We can just use the location
namespace the whole way through.

The original change to put zeroes directly into instructions created
conditional mov's with the zero immediate. However that can't be
emitted, so make sure to replace the zero with r63.

A situation where there's a 128-bit load where the last component gets
DCE'd causes a 96-bit load to be generated, which no GPU can actually
emit. Avoid generating such instructions by scaling back to 64-bit on
the first load when splitting.

This was just plain broken. It used always the value from v0 (for vp_index)
but would pass the value from the provoking vertex to later stages - but only
if there was a corresponding fs input, otherwise the layer/vp index would get
lost completely (as it would try to interpolate the (unsigned) values as
floats).
So, make it obey provoking vertex rules (drivers relying on draw will need to
do the same). And make sure that the default interpolation mode (when no
corresponding fs input is found) for them is constant.
Also, change the code a bit so constant inputs aren't interpolated then
copied over later.
Fixes the new piglit test gl-layer-render-clipped.
v2: more consistent whitespaces fixes for function defs, and more tab killing
(overall still not quite right however).

d3d10 actually requires using provoking (first) vertex. GL is happy with
any vertex (as long as we say it's undefined in the corresponding queries).
Up to now we actually used vertex 0 for viewport index, and vertex 1 for
layer (for tris), which really didn't make sense (probably a typo). Also,$
since we reorder vertices of clockwise triangle, that actually meant we used
a different vertex depending if the traingle was cw or ccw (still ok by gl).
However, it should be consistent with what draw (clip) does, and using
provoking vertex seems like the sensible choice (draw clip will be fixed
next as it is totally broken there).
While here, also use the correct viewport always even when not needed
in setup (we pass it down to jit fragment shader it might be needed there
for getting correct near/far depth values).
No piglit changes.

Currently it stores strlen(buf) whenever the user originally provided a
negative value for length.
Although I've not seen any explicit text in the spec, CTS requires that
the very same length (be that negative value or not) is returned back on
Pop.

gl_debug_message::length and fix GetDebugMessageLog to add and count the
null terminators, as required by the spec.

These new (relative to ARB_debug_output) tokens, have been explicitly

to glDebugMessageInsert was dropped.
At the same time, further down the spec says:
"The value of <type> must be one of the values from Table 5.4"
... and these two are listed in Table 5.4.
The GL 4.3 and GLES 3.2 do not give any hints on the former
'definition', plus CTS requires that the tokens are valid values for
