Subject: AArch64: support SwiftCC properly on AAPCS64

The previous SwiftCC support for AAPCS64 was partially correct.  It
setup swiftself parameters in the proper register but failed to setup
swifterror in the correct register.  This would break compilation of
swift code for non-Darwin AAPCS64 conforming environments.
