90a8b792c0 glsl: Implement constant expr evaluation for bitwise-not 
Implement by adding a case to ir_expression::constant_expression_value()
for ir_unop_bit_not.

720bdfbceb glsl: Initialize variable in ir_derefence_array::constant_expression_value 
Completely initialize data passed to ir_constant constructor.

Fixes piglit glsl-mat-from-int-ctor-03 valgrind uninitialized value
error on softpipe.

6ea16b6c51 glsl: Fix broken handling of ir_binop_equal and ir_binop_nequal. 
When ir_binop_all_equal and ir_binop_any_nequal were introduced, the
meaning of these two opcodes changed to return vectors rather than a
single scalar, but the constant expression handling code was incorrectly
written and only worked for scalars.  As a result, only the first
component of the returned vector would be properly initialized.

4dfb89904c glsl: introduce ir_binop_all_equal and ir_binop_any_equal, allow vector cmps 
Currently GLSL IR forbids any vector comparisons, and defines "ir_binop_equal"
and "ir_binop_nequal" to compare all elements and give a single bool.

This is highly unintuitive and prevents generation of optimal Mesa IR.

Hence, first rename "ir_binop_equal" to "ir_binop_all_equal" and
"ir_binop_nequal" to "ir_binop_any_nequal".

Second, readd "ir_binop_equal" and "ir_binop_nequal" with the same semantics
as less, lequal, etc.

Third, allow all comparisons to acts on vectors.

f412fac5b4 glsl: Move is_builtin flag back to ir_function_signature. 
This effectively reverts b6f15869b3.

In desktop GLSL, defining a function with the same name as a built-in
hides that built-in function completely, so there would never be
built-in and user function signatures in the same ir_function.

However, in GLSL ES, overloading built-ins is allowed, and does not
hide the built-in signatures - so we're back to needing this.

b6f15869b3 glsl: Move is_built_in flag from ir_function_signature to ir_function. 
Also rename it to "is_builtin" for consistency.

5e9ac94cc4 mesa: Add new ir_unop_any() expression operation. 
The previous any() implementation would generate arg0.x || arg0.y ||
arg0.z.  Having an expression operation for this makes it easy for the
backend to generate something easier (DPn + SNE for 915 FS, .any
predication on 965 VS)

d12cb77d85 ir_constant_expression: Implement equal/notEqual for booleans. 
Calls to equal(bvec, bvec) or notEqual(bvec, bvec) previously caused an
assertion.  Fixes piglit tests glsl-const-builtin-equal-bool and
glsl-const-builtin-notEqual-bool.

8273bd4687 glsl2: Make the clone() method take a talloc context. 
In most cases, we needed to be reparenting the cloned IR to a
different context (for example, to the linked shader instead of the
unlinked shader), or optimization before the reparent would cause
memory usage of the original object to grow and grow.
