History
John Stiles 108bbe2522 Optimize away swizzles on single-argument constructors. 
The optimizer can now turn the expression `half4(1).xyz` into
`half3(1)`, or `half4(1).w` into `1`. This is actually a somewhat common
case when inlining chains of fragment processors, as inputs are often
overridden to `half4(1)` or `half4(0)`. This optimization also applies
to more complex cases, e.g.:

     `half2(anyFunc(sqrt(2))).yxyx` --> `half4(anyFunc(sqrt(2)))`

Since the interior of the constructor is always evaluated once in either
case, it does not actually matter what the constructor contains.
