Log Message:
lint: do not allow assignment-expression for constant-expression

It's a funny idea to do something like 'case a = 13:', but since any
compiler will reject this code, there is no point in lint supporting it.

No functional change since everywhere the grammar allows a constant
expression, there is no ambiguity where an assignment could be
interpreted differently.
