Fix TestNoGPacketSupported on linux
The mock server pretends the process stopped with signal 17, which is 
SIGCHLD on linux. This causes lldb to resume to process, utterly 
confusing the test. Lldb probably shouldn't resume in this case, but for 
now this issue can be fixed by changing the signal number to 2, which is 
SIGINT just about anywhere.

[ObjC] Override TailCallKind when lowering objc intrinsics
The tail-call-kind-ness is known by the ObjCARC analysis and can be 
enforced while lowering the intrinsics to calls.
This allows us to get the requested tail calls at -O0 without trying to 
preserve the attributes throughout passes that change code even at -O0
,like the Always Inliner, where the ObjCOpt pass doesn't run.
