Summary: This change fixes the XRay trampolines aside from the __xray_CustomEvent trampoline to align the stack to 16-byte boundaries before calling the handler. Before this change we've not been explicitly aligning the stack to 16-byte boundaries, which makes it dangerous when calling handlers that leave the stack in a state that isn't strictly 16-byte aligned after calling the handlers. We add a test that makes sure we can handle these cases appropriately after the changes, and prevents us from regressing the state moving forward. Fixes http://llvm.org/PR35294.
