Robert Widmann 847930bfb7 Don't Force the Interface Type While Checking Sendable ...

Asking for Sendable conformances on this path is going to lead to
a traversal of the stored properties of the type. If there is an
interface type computation ongoing, as is very likely the case, this
traversal can wind up causing a cycle when it forces the interface type
of a member once again.

Request only the non-structural conformances to break the cycle.
