lowerConstant() currently accepts a number of constant expressions which have corresponding MC expressions, but which cannot be evaluated as a relocatable expression (unless the operands are constant, in which case we'll just fold the expression to a constant). The motivation here is to clarify which constant expressions are really needed for https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179, and in particular clarify that we do not need to support any division expressions, which are particularly problematic.
