This patch is needed to add support to clang's AVR ABI for the Swift language.
It is a pre-requisite for adding AVR support to the public Swift compiler
itself.
I'm open to any suggestions how I might create suitable unit tests for this?

Subject: [PATCH] [AVR] make the AVR ABI Swift compatible
This patch is needed to add support to clang's AVR ABI for the Swift
language. It is a pre-requisite for upstreaming AVR patches to the Swift
