[semantic-sil] Remove CleanupHandle from forBorrowed*RValue methods.
[semantic-sil] Remove CleanupHandle from forBorrowed*RValue methods.

I realized over the weekend the follie of storing a borrowed cleanup on
ManagedValues themselves. The reasons for this are:

1. We assume all over SILGen that ManagedValue::hasCleanup() => Owned. I would
have to fix all of those parts of the compiler.
2. The reason for having a cleanup handle on ManagedValue is to be able to
forward owned arguments, so there is really no purpose since we never want to be
able to forward these arguments.
