Joe Groff 66a2b6a0e2 SILGen: Purge misuses of pre-exploded RValue constructor. ...

The RValue(ArrayRef<ManagedValue>, CanType) constructor was intended as a semi-private interface for building an RValue from a pre-exploded array of elements, but was (understandably) widely being misused as a general ManagedValue-to-RValue constructor, causing crashes when working with tuples in various contexts where RValue's methods expected them to be exploded. Make the constructor private and update most improper uses of it to use the exploding RValue constructor, or to use a new `RValue::withPreExplodedElements` static method that more explicitly communicates the intent of the constructor. Fixes rdar://problem/29500731.
