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.

c8babd5d9b glsl2: Fix typo in clamp() constant builtin using uint instead of int. 
I take back the bad things I've said about the signed/unsigned
comparison warning now.

5704ed27dd glsl2: Don't consider uniform initializers as constant expressions. 
We were happily optimizing away the body of
glsl-uniform-initializer-* to never use the uniforms.

a7650af706 ir_constant_expression: Simplify code that implements the "dot" builtin. 
There's no need to use an ir_expression; we have a handy C function.

4b1d77ea96 ir_constant_expression: Remove support for dot products of integers. 
This shouldn't be required since dot is only defined for floating point
types, even in GLSL 4.0.

8b1680acc3 ir_constant_expression: Implement builtins that wrap an expression. 
These builtin functions are represented by ir_expression_operations, so
we can just create one of those and ask for its value.

38cb1b273f ir_constant_expression: Add support for builtins dFdx, dFdy, and fwidth. 
These always return zero (the derivative of a constant).

54f583a206 glsl2: Don't dereference a NULL var in CE handling during a compile error. 
If an undeclared variable was dereferenced in an expression that
needed constant expression handling, we would walk off a null ir->var
pointer.

3e882ec84a ir_constant_expression: Fix broken code for floating point modulus. 
It's supposed to be x - y * floor(x/y), not (x - y) * floor(x/y).

9a6d40fbfb ir_constant_expression: Add support for array == and !=.

generate the correct code.

46d6b8d1ba ir_constant_expression: Add support for ir_unop_u2f.

3163f87463 ir_constant_expression: Remove open coded equality comparisons. 
The ir_constant::has_value method already does this.

e4768eecd5 ir_constant_expression: Remove pointless use of variable_referenced. 
ir_dereference_variable always references an ir_variable, so there's no
point in calling a function and NULL-checking the result.

98f32a13be ir_constant_expression: Use "this" pointer directly. 
In ir_expression's signature, I replaced ir->operands[i] with op[i] as
it is more concise; an assertion already ensures these are equal.

fb2ffd2846 ir_constant_expression: Convert from a visitor to a virtual function. 
The constant_expression_wrapper was already the only external API, and
much of the internal code used it anyway.  Also, it wouldn't ever visit
non-rvalue ir_instructions, so using a visitor seemed a bit unnecessary.

This uses "ir_foo *ir = this;" lines to avoid code churn.  These should
be removed.

e340854115 glsl2: Move constant_expression_value method to ir_rvalue. 
This prevents top-level callers from asking for the value of something
that is guaranteed not to have one.
