Joe Groff a3a54545e5 SIL: Fix up ownership and bridging when emitting dynamic method calls. ...

There were a bunch of things broken here--it's amazing this ever appeared to work.

- Retain 'self' before partial_applying it to the method, so we don't overrelease it.
- Correctly lower the ownership conventions of the dynamic method against the SILDeclRef, so we don't overrelease arguments or over-over-release self, and we handle ObjC methods with weird conventions correctly.
- Thunk when there are bridging type differences between the partially-applied ObjC method and a Swift method, so we don't crash if the method takes NSStrings or other bridged types.

Add verifier checks that the result of 'dynamic_method' and BB arg of 'dynamic_method_br' actually match the method they're dispatching.
