[PATCH] D18869: AArch64: Use a callee save registers for swiftself parameters

[Matthias Braun via llvm-commits]

MatzeB added a comment.

I just realized that there are radars that propose x19 to be used for swifterror. We can of course change the register. The important parts are the bits that allow to pass values in callee saved registers.
