ir_constant_visitor: Type of constant result is same as original expression
...
The type of the resulting constant must be the same as the type of the
original expression. The changes to the code require that the case
where an unhandled expression is received, and there really shouldn't
be any of these, must be an exit point.

ir_constant_visitor: Types of ir_binop_{equal,nequal} must match
...
The types must match exactly, so there is no reason to check the types here.

Add ir_loop to represent loops
