glsl: Rework lowering of non-constant array indexing

dereference.  For example:

    mat4 m[2];

Due to the way it tracked whether the array was being assigned, it
would think that the non-constant index was in an r-value.  The new
code fixes that by tracking l-values and r-values differently.  The
index is also replaced by cloning the IR and replacing the index
variable instead of the odd way it was done before.

v2: Apply some simplifications suggested by Eric Anholt.  Making

intel: Fix stencil buffer to be W tiled

Until now, the stencil buffer was allocated as a Y tiled buffer, because
in several locations the PRM states that it is. However, it is actually
W tiled. From the PRM, 2011 Sandy Bridge, Volume 1, Part 2, Section
4.5.2.1 W-Major Format:
    W-Major Tile Format is used for separate stencil.

The GTT is incapable of W fencing, so we allocate the stencil buffer with
I915_TILING_NONE and decode the tile's layout in software.

This fix touches the following portions of code:
    - In intel_allocate_renderbuffer_storage(), allocate the stencil
      buffer with I915_TILING_NONE.
    - In intel_verify_dri2_has_hiz(), verify that the stencil buffer is
      not tiled.
    - In the stencil buffer's span functions, the tile's layout must be
      decoded in software.

float foo(float x) { return abs(x); }
float abs(float x) { return -x; }
float bar(float x) { return abs(x); }

This seems insane, but it matches what the spec says.
