The idea is to allow 32 normal varyings and 32 patch varyings,
a total of 64. Previously, only a total of 32 was allowed.

In commit 8fc41df (glsl: Modify ir_set_program_inouts to handle
geometry shaders), when attempting to pattern match the "foo" part of
expressions such as:
foo[i][j]
foo[i]
I incorrectly called as_dereference_variable() on the subexpression
foo[i] instead of foo. As a result, the pattern never matched, so
ir_set_program_inouts would fall back on marking the entire variable
as used, rather than just the portion indexed by the array.
This didn't result in incorrect behaviour, but it could have resulted
in inefficiency by causing the back-end to allocate resources for
unused parts of an input or output array.

According to GLSL, indexing into an array or matrix with an
out-of-range constant results in a compile error. However, indexing
with an out-of-range value that isn't constant merely results in
undefined results.
Since optimization passes (e.g. loop unrolling) can convert
non-constant array indices into constant array indices, it's possible
that ir_set_program_inouts will encounter a constant array index that
is out of range; if this happens, just mark the whole array as used.

The code in ir_set_program_inouts that marks just a portion of a
variable as used (rather than the whole variable) only works on a few
kinds of indexing operations:
- Indexing into matrices
- Indexing into arrays of matrices, vectors, or scalars.
Fortunately these are the only kinds of indexing operations that we
expect to see; everything else is either handled by a
previously-executed lowering pass or prohibited by GLSL.
However, that could conceivably change in the future (the GLSL rules
might change, or we might modify the lowering passes). To avoid
mysterious bugs in the future, let's have ir_set_program_inouts report
an assertion failure if it ever encounters an unexpected kind of
indexing operation (and in release builds, fall back to just marking
the whole variable as used).

Back when ir_var_in and ir_var_out signified both function parameters
and shader input/outputs, we had trouble distinguishing the two when
looking at a dereference. Now that we have separate ir_var_shader_in
and ir_var_shader_out modes, we can determine this easily.
Removing the hash table saves memory and CPU overhead.

This patch replaces the three ir_variable_mode enums:
- ir_var_in
- ir_var_out
- ir_var_inout
with the following five:
- ir_var_shader_in
- ir_var_shader_out
- ir_var_function_in
- ir_var_function_out
- ir_var_function_inout
This eliminates a frustrating ambiguity: it used to be impossible to
tell whether an ir_var_{in,out} variable was a shader in/out or a
function in/out without seeing where the variable was declared in the
IR. This complicated some optimization and lowering passes, and would
have become a problem for implementing varying structs.
In the lisp-style serialization of GLSL IR to strings performed by
ir_print_visitor.cpp and ir_reader.cpp, I've retained the names "in",
"out", and "inout" for function parameters, to avoid introducing code
churn to the src/glsl/builtins/ir/ directory.
Note: a couple of comments in the code seemed to indicate that we were
planning for a possible future in which geometry shaders could have
shader-scope inout variables. Our GLSL grammar rejects shader-scope
inout variables, and I've been unable to find any evidence in the GLSL
standards documents (or extensions) that this will ever be allowed, so
I've eliminated these comments.

Previously, the code for setting this flag for GLSL programs was
duplicated in three places: brw_link_shader(), glsl_to_tgsi_visitor,
and ir_to_mesa_visitor. In addition to the unnecessary duplication,
there was a performance problem on i965: brw_link_shader() set the
flag before doing its final round of optimizations, which meant that
if the optimizations managed to eliminate all the discard operations,
the flag would still be set, resulting (at least in theory) in slower
performance.
This patch consolidates all of the code that sets UsesKill for GLSL
programs into do_set_program_inouts(), which already is doing a
similar job for UsesDFdy, and which occurs after i965's final round of
optimizations.
Non-GLSL programs (ARB programs and the state tracker's glBitmap
program) are unaffected.

This patch updates the ir_set_program_inouts_visitor so that it also
sets gl_fragment_program::UsesDFdy.
This is a bit of a hack (since dFdy() isn't an input or an output),
but there's no other obvious visitor to squeeze this functionality
into, and it would be silly to create a brand new visitor just for
this purpose.
v2: use local 'fprog' var to avoid repeated casting.

This adds index support to the GLSL compiler.
I'm not 100% sure of my approach here, esp without how output ordering
happens wrt location, index pairs, in the "mark" function.
Since current hw doesn't ever have a location > 0 with an index > 0,
we don't have to work out if the output ordering the hw requires is
location, index, location, index or location, location, index, index.
But we have no hw to know, so punt on it for now.
v2: index requires layout - catch and error
setup explicit index properly.
v3: drop idx_offset stuff, assume index follow location

This patch makes GLSL interpolation qualifiers visible to drivers via
the array InterpQualifier[] in gl_fragment_program, so that they can
easily be used by driver back-ends to select the correct interpolation
mode.
Previous to this patch, the GLSL compiler was using the enum
ir_variable_interpolation to represent interpolation types. Rather
than make a duplicate enum in core mesa to represent the same thing, I
moved the enum into mtypes.h and renamed it to be more consistent with
the other enums defined there.

Having a few of these includes or forward declarations inside the
'extern "C"' block can cause problems later. Specifically, it
prevents C++ linkage functions from being added to ir_to_mesa.h and
makes G++ angry if 'struct foo' is seen both inside and outside an
'extern "C"'.
