When we take the self value out of the box inside a
RebindSelfInConstructorExpr, zero out the box right away
instead of doing it right before the apply or try_apply
instruction.
This way, if we have to emit a try_apply while while
evaluating arguments, we don't double-free the self
value.
Also, teach DI about releases of loads from the self box,
since now we might release the uninitialized self this
way.
This change also lets us get rid of some weird code.

Add a new convention to describe what happens with
nonzero_result on a type that isn't imported as Bool.
This isn't really a safe convention to implement, but
calls are fine.

Then use that to ban NSError.init(), because it doesn't create a valid
NSError. In the long run Foundation will hopefully add this to their
headers, but they can't yet (rdar://problem/19977891).

results when finding bridged types, rather than reinventing
(well, pre-inventing) the same thing elsewhere.
Doing this apparently forces AbstractionPattern to deal
with ObjC protocol methods for the first time, which are
generic and therefore require even the Clang-based
abstraction patterns to propagate generic signatures.
Use this infrastructure to allow foreign error conventions
to suppress the wrapping of nonnull bridged collection results
in a level of optionality. We can't treat nil results as
an empty collection while simultaneously treating them as
an error signal.
