d67515b7be glsl: remove element_type() helper
We now have is_array() and without_array() that make the
code much clearer and remove the need for this.

For all remaining calls to this we already knew that
the type was an array so returning a null wasn't adding any value.

v2: use without_array() in _mesa_ast_array_index_to_hir() and don't use
 without_array() in lower_clip_distance_visitor() as we want to make sure the
 array is 2D.

9f1e250e77 glsl: Mark array access when copying to a temporary for the ?: operator.
Piglit's spec/glsl-1.20/compiler/structure-and-array-operations/
array-selection.vert test contains the following code:

   gl_Position = (pick_from_a_or_b ? a : b)[i];

where "a" and "b" are uniform vec4[2] variables.

ast_to_hir creates a temporary vec4[2] variable, conditional_tmp, and
generates an if-block to copy one or the other:

   (declare (temporary) (array vec4 2) conditional_tmp)
   (if (var_ref pick_from_a_or_b)
     ((assign () (var_ref conditional_tmp) (var_ref a)))
     ((assign () (var_ref conditional_tmp) (var_ref b))))

However, we failed to update max_array_access for "a" and "b", so it
remained 0 - here, the whole array is being accessed.  At link time,
update_array_sizes() used this bogus information to change the types
of "a" and "b" to vec4[1].  We then had assignments from a vec4[1] to
a vec4[2], which is highly illegal.

This tripped assertions in nir_split_var_copies with scalar VS.

187ace73a9 glsl: A shader cannot redefine or overload built-in functions in GLSL ES 3.00
Create a new search function to look for matching built-in functions by name
and use it for built-in function redefinition or overload in GLSL ES 3.00.

GLSL ES 3.0 spec, chapter 6.1 "Function Definitions", page 71

  "A shader cannot redefine or overload built-in functions."

While in GLSL ES 1.0 specification, chapter 8 "Built-in Functions"

  "User code can overload the built-in functions but cannot redefine them."

So this check is specific to GLSL ES 3.00.

This patch fixes the following dEQP tests:

dEQP-GLES3.functional.shaders.functions.invalid.overload_builtin_function_vertex
dEQP-GLES3.functional.shaders.functions.invalid.overload_builtin_function_fragment
dEQP-GLES3.functional.shaders.functions.invalid.redefine_builtin_function_vertex
dEQP-GLES3.functional.shaders.functions.invalid.redefine_builtin_function_fragment

No piglit regressions.

0f06f12c11 glsl: Pick ast_conditional branch regardless of op1/2 being constant.
If the ?: operator's condition is a constant value, and both branches
were pure expressions, we can just make the resulting value one or the
other.

Previously, we only did this if op[1] and op[2] were also constant
values - but there's no actual reason for that restriction.

No changes in shader-db, probably because we usually optimize this later
anyway.  But it does make us generate less stupid code up front.

14379a0644 glsl: fix several use-after-free bugs
The get_variable_being_redeclared() function can free the 'var' argument.
Thereafter, we cannot assume that 'var' is a valid  pointer.  This patch
replaces 'var->name' with 'earlier->name' in two places and calls
is_gl_identifier(var->name) before 'var' might get freed.

This fixes several piglit GLSL crashes, including:
spec/glsl-1.50/execution/geometry/clip-distance-in-param
spec/glsl-1.50/execution/geometry/clip-distance-bulk-copy
spec/glsl-1.50/compiler/gs-redeclares-pervertex-out-before-global-redeclaration.geom

continue for the outside loop.

3d051772c8 glsl: Only create one ir_function for a given name.
Piglit's spec/glsl-1.10/linker/override-builtin-{const,uniform}-05 tests
do the following:

1. Call abs(float) - a built-in function.
2. Create a user-defined replacement for abs(float).
3. Call abs(float) again - now the user function.

At step 1, we created an ir_function which included the built-in
signature, added it to the symbol table, and emitted it into the IR
stream.

Then, when processing the function definition at step 2, we'd see that
there was already an ir_function.  But, since there were no user-defined
functions, we skipped over a bunch of code, and ended up creating a
second one.  This new ir_function shadowed the original in the symbol
table, but both ended up in the IR stream.

This results in an awkward situation where searching for an ir_function
via the symbol table, a forward linked list walk, and a reverse linked
list walk may return different ir_functions.  This seems undesirable.

This patch instead re-uses the existing ir_function, putting both
built-in and user-defined signatures in the same one.  The previous
patch's additional filtering ensures everything continues working.
