intel: Clean up confusion between logical and physical surface dimensions.
In most cases, the width, height, and depth of the physical surface
used by the driver to implement a texture or renderbuffer is equal to
the logical width, height, and depth exposed to the client through
functions such as glTexImage3D(). However, there are two exceptions:
cube maps (which have a physical depth of 6 but a logical depth of 1)
and multisampled renderbuffers (which have larger physical dimensions
than logical dimensions to allow multiple samples per pixel).
Previous to this patch, we accounted for the difference between
physical and logical surface dimensions at inconsistent places in the
call graph (multisampling was accounted for in
intel_miptree_create_for_renderbuffer(), and cubemaps were accounted
for in intel_miptree_create_internal()). As a result, it wasn't
always clear, when calling a miptree creation function, whether
physical or logical dimensions were needed. Also, we weren't
consistent about storing logical dimensions in the intel_mipmap_tree
structure (we only did so in the
intel_miptree_create_for_renderbuffer() code path, and we did not
store depth).
This patch refactors things so that intel_miptree_create_internal() is
responsible for converting logical to physical dimensions and for
storing both the physical and logical dimensions in the
intel_mipmap_tree structure. As a result, all miptree creation
functions interpret their arguments as logical dimensions, and both
physical and logical dimensions are always available to functions that
work with intel_mipmap_trees.
In addition, it renames the fields in intel_mipmap_tree used to store
the dimensions, so that it is clear from the name whether physical or
logical dimensions are being referred to.
This should fix the following bugs:
- When creating a separate stencil surface for a depthstencil cubemap,
we would erroneously try to convert the depth from 1 to 6 twice,
resulting in an assertion failure.
- When creating an MCS buffer for compressed multisampling, we used
physical dimensions instead of logical dimensions, resulting in
wasted memory.
In addition, this should considerably simplify the implementation of
ARB_texture_multisample, because it moves the code to compute the
physical size of multisampled surfaces out of renderbuffer-only code.

glsl: Pack flat "varyings" of mixed types together.
This patch enhances the varying packing code so that flat varyings of
uint, int, and float types can be packed together.
We accomplish this in lower_packed_varyings.cpp by making the type of
all flat varyings ivec4, and then using information-preserving type
conversions (e.g. ir_unop_bitcast_f2i) to convert all other types to
ints.
The varying_matches::compute_packing_class() function is updated to
reflect the fact that varying packing no longer needs to segregate
varyings of different base types.

v2: Split lower_packed_varyings_visitor::bitwise_assign into

glsl: Prohibit structs and bools from being used as "varyings".
The GLSL 1.30 spec only allows vertex shader outputs and fragment
shader inputs ("varyings" in pre-GLSL-1.30 parlance) to be of type
int, uint, float, or vectors, matrices, or arrays thereof. Bools,
bvec's, and structs are prohibited. (Integral varyings were
prohibited prior to GLSL 1.30).
Previously, Mesa only performed this check on variables declared with
the "varying" keyword, and it always performed the check according to
the pre-GLSL-1.30 rules. As a result, bools and structs were allowed
to slip through, provided they were declared using the new in/out
syntax.
This patch modifies the error check so that it occurs after "varying"
is converted to "in/out", and corrects it to properly account for GLSL
version.
