Use ir_function::add_signature to create link between function and signature
...
ir_function_signature now has a pointer back to the ir_function that owns it.

Implement ir_if (for if-statments) and conversion from AST
...
The following tests now pass:
glslparsertest/shaders/if1.frag
glslparsertest/shaders/if2.frag
The following tests that used to pass now fail. It appears that most
of these fail because ast_nequal and ast_equal are not converted to HIR.
shaders/glsl-unused-varying.frag
shaders/glsl-fs-sqrt-branch.frag

Implement exp2() and log2(), and make ir_unop_exp and ir_unop_log be base e.
...
Making the base e functions IR operations is not a clear win. i965
doesn't support it, it doesn't look like r600 supports it, but r500
does. It should be easily supportable as a lowering pass, though.

Add sqrt() builtin as an IR operation.
...
Following a discussion in #dri-devel, I think this makes more sense
than implementing it as RSQ RCP CMP as Mesa did. The i965 has a
hardware sqrt that should work, and AMD is suppposed to be able to
implement it as RSQ RCP with an alternate floating point mode so that
the 0.0 case is handled like we want.

This should fix tests trying to assign to builtin "in" variables, and

Move swizzles out of ir_dereference and into their own class.
...
Also turn generate_swizzle into a static "create" method of the new
class; we'll want to use it for the IR reader as well.
