Fix #3067: GHCi panics with 'initTc:LIE' while :stepping on code with funny types
Fix #3067: GHCi panics with 'initTc:LIE' while :stepping on code with funny types

The problem is that calls to boxyUnify would panic if the types involved
contained type functions. 
It looks like one should wrap these calls with getLIE, although I don't
really know what I am doing here
