Yes, this is a dupe of PR11352. We take the ConstantExpr "i32* getelementptr
inbounds (%closure* @f, i32 0, i32 0)" verbatim when processing the store, but
when processing the load in @lambda, it globalopt computes that exact same
constant-expr but feeds it through ConstantFoldConstantExpression which
produces "i32* getelementptr inbounds (%closure* @f, i64 0, i32 0)", which
appears to GlobalOpt to be an entirely different pointer.
