Joe Groff 0cdbe89576 Fix some regressions with handling of blocks.

- If a @convention(block) function parameter was also marked @noescape, then during type-checking, we would accidentally propagate the convention directly onto a literal closure expr, instead of going through a function_conversion, which SILGen didn't handle. Fixes rdar://problem/23261912.
- If an Objective-C API declared a block parameter with a _Nonnull return of a bridged type, such as NSString *_Nonnull, then native-to-bridged thunking would fail to recognize this case, since we still bridge to an Optional type in the lowered ObjC interface. Fixes rdar://problem/23285766.
