History
John Stiles 0777ac4778 Optimize swizzled multiple-argument constructors. 
This will reorder constructors with swizzles applied, such as
    `half4(1, 2, 3, 4).xxyz` --> `half4(1, 1, 2, 3)`
    `half4(1, colRGB).yzwx` --> `half4(colRGB.x, colRGB.y, colRGB.z, 1)`

Note that, depending on the swizzle components, some elements of the
constructor may be duplicated and others may be eliminated. The
optimizer makes sure to leave the swizzle alone if it would duplicate
anything non-trivial, or if it would eliminate anything with a side
effect.
