This prepares for selectively enabling hiz on individual miptree slices

This refactoring had several side effects.

  1. To prevent new warnings about discarding the const qualifier,

     in the Intel code is to not qualify function parameters as const,
     I chose to remove rather than add const qualifiers.

  2. I changed the signature of brw_emit_depth_stencil_hiz() by replacing
     `struct intel_mipmap_tree *hiz_mt` with `bool hiz`. The function used

Commit dfb57e7 (glsl: Fix error checking on "flat" keyword to match
GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they
only need to be declared as "flat" if they are a fragment shader
inputs.  This allowed for the possibility of a vertex shader output
being a non-flat integer, provided that it was not matched to a
fragment shader input.  A non-contrived situation where this might
arise is if a vertex shader generates some integral outputs which are
consumed by tranform feedback, but not by the fragment shader.

Unfortunately, lower_packed_varyings assumes that *all* integral
varyings are flat, regardless of whether they are consumed by the
fragment shader.  As a result, attempting to create a non-flat
integral vertex output of a size that required packing (i.e. a size
other than ivec4 or uvec4) would cause an assertion failure in
lower_packed_varyings.

This patch prevents the assertion failure by forcing vertex shader
outputs to be "flat" whenever they are not consumed by the fragment
shader.  This should have no effect on rendering since the "flat"
keyword only affects the behaviour of fragment shader inputs.
