Despite the name, this field wasn't being set to the dispatch width at
all; it was always 8. The only place it was used was that the
constant buffer read length was aligned to it, and as far as I can
tell from the docs, there is no need to align this value to the
dispatch width; aligning it to a multiple of 8 is sufficient. So I've
just replaced it with a hardcoded 8.

This patch populates the following built-in GLSL 1.50 variables based
on constants stored in ctx->Const:
- gl_MaxVertexOutputComponents

- gl_MaxGeometryOutputComponents
- gl_MaxFragmentInputComponents
- gl_MaxGeometryTextureImageUnits
- gl_MaxGeometryOutputVertices
- gl_MaxGeometryTotalOutputComponents
- gl_MaxGeometryUniformComponents

gl_MaxGeometryUniformComponents.

It would be nice to be able to pack our binding table so that programs
that use 1 render target don't upload an extra BRW_MAX_DRAW_BUFFERS - 1
binding table entries. To do that, we need the compiled program to have
information on where its surfaces go.

* As discussed on the mailing list,
forced no-rtti breaks C++ public
API's such as the Haiku C++ libGL.so
* -fno-rtti *can* be still set however
instead of blindly forcing -fno-rtti,
we can rely on the llvm-config
--cppflags output.
If the system llvm is built without
rtti (default), the no-rtti flag will be
present in llvm-config --cppflags
(which we pick up on)
If llvm is built with rtti
(REQUIRES_RTTI=1), then -fno-rtti is
removed from llvm-config --cppflags.
* We could selectively add / remove rtti

This fixes the issue when dst and src is the same reg and operation on one
channel overwrites the source for other channels, e.g.:
UMUL TEMP[2].xyz, TEMP[0].xyzz, TEMP[2].xxxx
In this example the result of the operation on channel x is written in
TEMP[2].x and then used as a second source operand for channels y and z
instead of original value in TEMP[2].x.
This patch stores the results in temp reg and moves them to
dst after performing operation on all channels.

These make it easy to convert a floating point value to a fixed point

fractional part of the number.
It looks like core Mesa has similar functions already, but none that
allows an arbitrary number of fractional bits. The more generic version
is probably useful to everyone.

The idea is that struct brw_device_info should store statically-known

PCI ID table, we can easily grab the right structure.
This is basically the equivalent of intel_device_info in the kernel.
This patch also makes the new structure available from intel_screen, but
nothing uses it. Right now, it looks very redundant with existing
