glsl2: Fix the type of (1.0 - arg2) for mix(gen, gen, float).
...
Previously, we'd constant-fold up a value of vec4(1.0 - arg2, 0, 0, 0).
Fixes:
glsl1-mix(vec4) function

linker: Link built-in functions instead of including them in every shader
...
This is an invasive set of changes. Each user shader tracks a set of other
shaders that contain built-in functions. During compilation, function
prototypes are imported from these shaders. During linking, the
shaders are linked with these built-in-function shaders just like with
any other shader.

glsl2: Fix asin() implementation.
...
I'd flipped around the order of two operations in paren-balancing
adventures, and left out the multiply by sign(x) required for negative x.
Fixes:
glsl1-acos(vec4) function
glsl1-asin(vec4) function
glsl1-atan(vec4) function

glsl2: Make cross() be an expression operation.
...
ARB_fp, ARB_vp, Mesa IR, and the 965 vertex shader all have
instructions for cross. Shaves 12 Mesa instructions off of a
66-instruction shader I have.

glsl2: Add ir_unop_fract as an expression type.

Most backends will prefer seeing this to seeing (a - floor(a)), so
represent it explicitly.

glsl2: Fix up the implementation of fract() for vector types.
