5e832302dc i965: Move multiply by 4 for VS ATTR setup into the scalar backend.
The vec4 backend will want to count in units of vec4s, not scalar
components.  The simplest solution is to move the multiplication by 4
into the scalar backend.  This also improves consistency with how we
count varyings.

36764b6923 i965/nir: Inline remap_vs_attrs
Now that we have nice block iterators, there's no good reason for this
to be off on it's own.  While we're here, we convert to using the NIR
const index getters/setters instead of whacking const_index values
directly.

b86dba8a0e nir: Embed the shader_info in the nir_shader again
Commit e1af20f18a changed the shader_info
from being embedded into being just a pointer.  The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct.  This, however, has
caused a few problems:

 1) There are many things which generate NIR without GLSL.  This means
    we have to support both NIR shaders which come from GLSL and ones
    that don't and need to have an info elsewhere.

 2) The solution to (1) raises all sorts of ownership issues which have
    to be resolved with ralloc_parent checks.

 3) Ever since 00620782c9, we've been
    using nir_gather_info to fill out the final shader_info.  Thanks to
    cloning and the above ownership issues, the nir_shader::info may not
    point back to the gl_shader anymore and so we have to do a copy of
    the shader_info from NIR back to GLSL anyway.

All of these issues go away if we just embed the shader_info in the
nir_shader.  There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.

7a7ee40c2d nir/i965: add before ffma algebraic opts
This shuffles constants down in the reverse of what the previous
patch does and applies some simpilifications that may be made
possible from doing so.

Shader-db results BDW:

7499bc7fd7 i965: Replace OPT_V() with OPT().
We want to be able to check the progress of each pass and dump the NIR
for debugging purposes if it changed.

700bebb958 i965: Move the back-end compiler to src/intel/compiler
Mostly a dummy git mv with a couple of noticable parts:
 - With the earlier header cleanups, nothing in src/intel depends
files from src/mesa/drivers/dri/i965/
 - Both Autoconf and Android builds are addressed. Thanks to Mauro and
Tapani for the fixups in the latter
 - brw_util.[ch] is not really compiler specific, so it's moved to i965.

v2:
 - move brw_eu_defines.h instead of brw_defines.h
 - remove no-longer applicable includes
 - add missing vulkan/ prefix in the Android build (thanks Tapani)

v3:
 - don't list brw_defines.h in src/intel/Makefile.sources (Jason)
 - rebase on top of the oa patches
