I don't know if this would be appropriate to upstream though? I'm a bit inexperienced and don't know all the angles. It solves the problem and I'm able to produce roughly correct LLVM IR, which I can compile to 16 bit AVR assembly language. 
Here's the original source...

typealias IntegerLiteralType = UInt8
struct MyStruct {
var internal1: Int8
var internal2: Int8
var internal3: Int16
var internal4: Int16
var internal5: Int8
}
while(true) {
}
Producing the following LLVM IR...

Mostly it's working I think. It won't link at the moment due to missing runtime (swift_retain).
However, @Joe_Groff has a point, it would be really good to start figuring out how I might turn off metadata emission on this platform. Do you have any pointers where I might look first?
