[XRay][AArch64] More staging for tail call support in XRay AArch64 - in compiler-rt

Authored by rSerge on Jan 20 2017, 5:53 AM.



This patch provides a trampoline for function tail exit tracing. Still, it's staging because code 1 is passed to the handler function (indicating a normal exit) instead of 2, which would indicate tail exit. This is so until the logging part of XRay supports tail exits too.
