Serge Rogatch fa846a116e [XRay][AArch64] More staging for tail call support in XRay AArch64 - in compiler-rt 
Summary:
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.
