We here have an AND of a SUBREG of an LSHIFTRT. If that SUBREG is

inner mode, which includes some bits that should not be in the result.
Just give up in that case.

compiler: insert backend type conversion for closure func ptr
In Func_expression::do_get_backend when creating the backend
representation for a closure, create a backend type conversion to
account for potential differences between the closure struct type
(where the number of fields is dependent on the number of values
referenced in the closure) and the generic function descriptor type
(struct with single function pointer field).
