ir_constant: Eliminate 'void *' constructor

All of the places that had been using the (glsl_type *, void *)
constructor were actually passing an ir_constant_data for the
'void *'.  The code can be greatly simplified by replacing this
constructor with a (glsl_type *, ir_constant_data *) constructor.
This should also help prevent one class of invalid uses of the old
constructor.
