Optimize splat constructors containing const vars.

A constructor like `float3(five)` is not a compile-time constant, so we
miss optimization opportunities like folding. Constant variables inside
splat constructors are now replaced when optimization is on, so this
would optimize down to `float3(5.0)` and be eligible for folding.
