These were added in commit f2616e56, presumably in preparation for
translating ARB vp/fp into GLSL IR. That never happened, and neither did
a lowering pass that actually generated these instructions.

From GLSL 3.30 and GLSL ES 1.00 on, after processing the line
directive (including its new-line), the implementation should
behave as if it is compiling at the line number passed as
argument. In previous versions, it behaved as if compiling
at the passed line number + 1.

From GLSL 1.30.10, section 3.3 (Preprocessor):
"#line line source-string-number ... After processing this directive
(including its new-line), the implementation will behave as if it is
compiling at ... source string number source-string-number. Subsequent
source strings will be numbered sequentially, until another #line
directive overrides that numbering."
In the previous implementation the source number was always zero.
Subsequent source strings are still not numbered sequentially, because
in the glShaderSource implementation we are concatenating the source code
strings into one long string.

The NIR compiler frontend is an alternative to the TGSI f/e, producing
the same ir3 IR and using the same backend passes for scheduling, etc.
It is not enabled by default yet, as there are still some regressions.
To enable, use 'FD_MESA_DEBUG=nir'. It is enough to use with, for
example, xonotic or supertuxkart.
With the NIR f/e, scalarizing and a number of other lowering steps
happen in NIR, so we don't have to do them in ir3. Which simplifies the
f/e and allows the lowered instructions to pass through other
optimization stages.

Since NIR f/e currently encodes immediates in instructions (rather than
passing via const), we need to ensure that when const's are used the get
initialized to the proper values. Otherwise comparing NIR to TGSI
compiler, it will use proper immediate values in one case, and randomly
initialize values in the other. Which confuses ir3test.

Be smarter about propagating copies from const or immed, or with abs/neg
modifiers. Also, realize that absneg.s and absneg.f are really "fancy"
mov instructions.
This opens up the possibility to remove more copies. It helps the TGSI
frontend a bit, but will be really needed for the NIR f/e which builds
everything up in SSA form (ie. will *always* insert a mov from const or
immediate).
Signed-off-by: Rob Clark <robclark@freedesktop.org>
Even though in the end, they map to the same bits, the backend will need
to be able to differentiate float abs/neg vs integer abs/neg. Rather
than making the backend figure it out based on instruction opcode (which
when combined with mov/absneg instructions, can be awkward), just split
out different flags for each so the frontend can signal it's intentions
more clearly. Also, since (neg) for bitwise op's is actually a bitwise-
not, split it out into bnot flag.

If we want to use NIR from state trackers that don't already pull in the
whole of glsl (ie. anything other than mesa state tracker), we need a

who just want NIR but not all of glsl.

both a flt and slt with same src args, for example).

Commit 1a170980a0 started writing to q->data[4]/[5] but kept the
per-query space at 16, which meant that in some cases we would write
past the end of the buffer. Rotate by 32, like nvc0 does. This ensures
that we always have 32 bytes in front of us, and the data writes will go
