When checking framebuffer completeness, we test each attachment.
We verify that all attachments are consistent in terms of layers.
1. They must all be layered, or all non-layered
2. If they are layered, they must match in depth

With glFramebufferTexture, a renderbuffer may support
all layers of the texture, so we need the depth of the
renderbuffer to check for consistency which is required
for framebuffer completeness.

This like the fifth attempt to fix the issue.
Also with the new "validating" flag, we can set recalculate_inputs to FALSE
earlier in vbo_bind_arrays, because _mesa_update_state won't change it.

According to the Ivybridge PRM, Volume 4 Part 1, page 130, in the
section for the sample_d message: "The r coordinate contains the faceid,
and the r gradients are ignored by hardware."
This doesn't match GLSL, which provides gradients for all of the
coordinates. So we would need to do some math to compute the face ID
before using sample_d. We currently don't have any code to do that.
However, we do have a lowering pass that converts textureGrad to
textureLod, which solves this problem. Since textureGrad on three
components is sufficiently obscure, it's not a performance path.
For now, only handle samplerCubeShadow; we need tests for samplerCube
and samplerCubeArray.

Consider the following shader:
vec4 f(vec4 v) { return v; }
vec4 f(vec4 v);
The prototype exactly matches the signature of the earlier definition,
so there's absolutely no point in it. However, it doesn't appear to
be illegal. The GLSL 4.30 specification offers two relevant quotes:
"If a function name is declared twice with the same parameter types,
then the return types and all qualifiers must also match, and it is the
same function being declared."
"User-defined functions can have multiple declarations, but only one
definition."
In this case the same function was declared twice, and there's only one
definition, which fits both pieces of text. There doesn't appear to be
any text saying late prototypes are illegal, so presumably it's valid.
Unfortunately, it currently triggers an assertion failure:
ir_dereference_variable @ <p1> specifies undeclared variable `v' @ <p2>
When we process the second line, we look for an existing exact match so
we can enforce the one-definition rule. We then leave sig set to that
existing function, and hit sig->replace_parameters(&hir_parameters),
unfortunately nuking our existing definition's parameters (which have
actual dereferences) with the prototype's bogus unused parameters.
Simply bailing out and ignoring such late prototypes is the safest
thing to do.
Fixes Piglit's late-proto.vert as well as 3DMark/Ice Storm for Android.

The number of samples is already available in the miptree data
structure, so there's no need to pass it in.
I suspect this may fix a subtle bug because in one case
(intel_renderbuffer_update_wrapper) we were always passing zero for
num_samples, even though the buffer in question was not guaranteed to
be single-sampled. But I wasn't able to find a failing test case.
