nouveau: rename var name for nouveau_vieux to avoid conflict with nouveau

We want to require different versions for nouveau and nouveau_vieux.
autoconf will only check for NOUVEAU once if both drivers are enabled,
meaning both version checks don't get executed. Rename the nouveau_vieux
one to NVVIEUX to avoid the issue.

nv50/ir: copy joinAt when splitting both before and after

The current implementation only moves the joinAt when splitting after
the given instruction, not before it. So if you have a BB with

  foo
  instr
  bar
  joinat

and thus with joinAt set, we end up first splitting before instr, at
which point the instr's bb is updated to the new bb. Since that bb
doesn't have a joinAt set (despite containing one), when splitting after
the instr, there is nothing to copy over. Since the joinat will be in
the "split" bb irrespective of whether we're splitting before or after
the instruction, move it over in either case.

docs: update for llvmpipe fp64 support

Signed-off-by: Dave Airlie <airlied@redhat.com>

gallivm: add fp64 support. (v2.1)

This adds support for ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit to
llvmpipe.

Two things that don't mix well are SoA and doubles, see
emit_fetch_double, and emit_store_double_chan in this.

I've also had to split emit_data.chan, to add src_chan,
which can be different for doubles.

It handles indirect double fetches from temps, inputs, constants
and immediates. It doesn't handle double stores to indirects,
however it appears the mesa/st doesn't currently emit these,
it always does UARL/MOV combos, which will work fine.

tested with piglit, no regressions, all the fp64 tests seem to pass.

v2:
switch to using shuffles for fetch/store (Roland)
assert on indirect double stores - mesa/st never emits these (it uses MOV)
fix indirect temp/input/constant/immediates (Roland)

i965: Don't use GCC extension for ?: with only two operands.

From the "apparently I don't know C" files...GCC apparently supports:

    x ?: y

which is equivalent to

    x ? x : y

except that it doesn't cause side-effects to occur twice.  See:

i965/gen9: Allocate YF/YS tiled buffer objects

In case of I915_TILING_{X,Y} we need to pass tiling format to libdrm
using drm_intel_bo_alloc_tiled(). But, In case of YF/YS tiled buffers
libdrm need not know about the tiling format because these buffers
don't have hardware support to be tiled or detiled through a fenced
region. libdrm still need to know buffer alignment value for its use
in kernel when resolving the relocation.

Using drm_intel_bo_alloc_for_render() for YF/YS tiled buffers
satisfy both the above conditions.

V2: Delete min/max buffer size restrictions not valid for i965+.

util: port _mesa_strto[df] to C

_mesa_strtod and _mesa_strtof are only used from the GLSL compiler and
