i965 implements this with a single (multiple destination) instruction,
ADDC. Emitting ADDC directly from uaddCarry() would be ideal, but our
optimization passes don't know how to copy with expressions with
side-effects.
Radeon has an ADDC_UINT instruction that only generates the carry
bit. I've chosen to go this route and implement uaddCarry() by doing the
addition and the carry operations separately.

Calculates the carry out of the addition of two values and the
borrow from subtraction respectively. Will be used in uaddCarry() and
usubBorrow() built-in implementations.

The only GLSL extension that is not enabled is AMD_vertex_shader_layer.
I think the standalone-compiler could enable this (as shading language
support is complete), but no driver enables it.

Pull the data directly from the context like the other varying related

state didn't have a pointer to the context. There's no reason to do it
now days.

As of ARB_gpu_shader5, textureGather doesn't always read the
post-swizzle RED channel -- so we can't just look at the red swizzle
state.
Theoretically we could only flag the quirk if *some* green swizzle is in
use, but that's probably more trouble than it's worth.
