mesa: Track max enabled tex image unit

This gives us a better bound for some hot loops in the drivers than
MAX_COMBINED_TEXTURE_IMAGE_UNITS, which is ridiculously large on modern
hardware, and only getting worse as more shader stages are added.

i965: Use ctx->Texture._MaxEnabledTexImageUnit for upper bound

Avoid looping over 32/48/96 (!!) tex image units every draw, most of
which we don't care about.

Improves performance on everyone's favorite not-a-benchmark by 2.9% on
Haswell.

st/mesa: fix invalid pointer use in st_texture_get_sampler_view()

The '**used' pointer was pointing into the stObj->sampler_views array.
If 'free' was null, we'd realloc that array, thus making the 'used'
pointer invalid.  This soon led to memory errors.

Just change the pointer to be '*used' so it points directly at the
pipe_sampler_view.

mesa: Add an error condition in glGetFramebufferAttachmentParameteriv()

From the OpenGL 4.4 spec page 275:
  "If pname is FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE, param will
   contain the format of components of the specified attachment,
   one of FLOAT, INT, UNSIGNED_INT, SIGNED_NORMALIZED, or
   UNSIGNED_NORMALIZED for floating-point, signed integer,
   unsigned integer, signed normalized fixedpoint, or unsigned
   normalized fixed-point components respectively. If no data
   storage or texture image has been specified for the attachment,
   param will contain NONE. This query cannot be performed for a
   combined depth+stencil attachment, since it does not have a
   single format."

Section 4.3.1, page 220, of OpenGL 3.3 specification explains
the error conditions for glreadPixels():

   "If the format is DEPTH_STENCIL, then values are taken from
    both the depth buffer and the stencil buffer. If there is
    no depth buffer or if there is no stencil buffer, then the
    error INVALID_OPERATION occurs. If the type parameter is

glsl: Only allow `invariant` on shader in/out between stages.

Previously this was special-cased for VS and FS; it never got updated
when geometry shaders came along. Generalize using is_varying_var() so
this won't be broken again with tessellation.

Note that there are two copies of the logic for `invariant`: It can be
present as part of a new declaration, and also as a redeclaration of an
existing variable or block member.

Fixes the four new piglits:
   spec/glsl-1.50/compiler/invariant-qualifier-*.geom

Note for stable: This won't quite pick cleanly due to whitespace and
state->target -> state->stage renames. Should be straightforward
adjustments though.

radeonsi: Fix calculation of number of banks for SI

The way cik_num_banks() was calculating the index only makes sense for
the CIK specific macrotile mode array. For SI, we need to use the tile
mode index directly.

This happened to work most of the time because most of the SI tiling
modes use the same number of banks.
