c9e9c224 - SILGen: Add explicit 'self' metadata parameter when 'self' is a mutable capture

SILGen: Add explicit 'self' metadata parameter when 'self' is a mutable capture If a closure uses DynamicSelfType but doesn't capture the 'self' value itself, we would add a dummy metatype capture so that IRGen can recover metadata. Also do this if we do capture a value of DynamicSelfType, but mutably, that is by address or by box, since IRGen doesn't know how to recover the metadata in that case. Fixes <rdar://problem/32288771>.
