A cast like `float(five)` or `int4(colorGreen)` will now detect const
variables and replace the expression with its compile-time constant
equivalent value. This can unblock further constant folding
opportunities.

A cast like `float(five)` or `int4(colorGreen)` should detect const
variables and replace the expression with its compile-time constant
equivalent value. At present, this replacement is missed, which inhibits
further optimization opportunities on the expression.
