i965/fs: Relax fs_builder channel group assertion when force_writemask_all is on.

This assertion was meant to catch code inadvertently escaping the
control flow jail determined by the group of channel enable signals
selected by some caller, however it seems useful to be able to
increase the default execution size as long as force_writemask_all is
enabled, because force_writemask_all is an explicit indication that
there is no longer a one-to-one correspondence between channels and

  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.

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:

mesa/glsl: new compiler option EmitNoIndirectSampler

Patch provides new compiler option for backend to force unroll loops
that have non-constant expression indexing on sampler arrays.

This makes sure that we can never end up with a shader that uses loop
induction variable as sampler array index but does not unroll because
of having too much instructions. This would not work without dynamic
indexing support.

v2: change option name as EmitNoIndirectSampler

glsl: Allow dynamic sampler array indexing with GLSL ES < 3.00

Dynamic indexing of sampler arrays is prohibited by GLSL ES 3.00.
Earlier versions allow 'constant-index-expression' indexing, where
index can contain a loop induction variable.

Patch allows dynamic indexing for sampler arrays when GLSL ES < 3.00.
This change makes 'sampler-array-index.frag' parser test in Piglit
pass + fishgl.com works when running Chrome on OpenGL ES 2.0 backend

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
