Flatten out constructors nested inside constructors.
- float4(float2(1, 2), 3, 4) --> float4(1, 2, 3, 4)
- half3(z, half2(fn(x), y*2)) --> half3(z, fn(x), y*2)
Single-argument constructors will be ignored by this optimization; these
might be casts or splats.
This had an unexpected side benefit of simplifying some Metal output,
as we need to output fewer Metal matrix construction helper functions
when matrices use more simple scalars for construction.

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.
