Log Message:
-----------
Fix instrumentation regressions for libc-2.29 on ARM (#653)
* Fixes loading pre-instrumentation register values on aarch64
* Fix the handling of trap instruction on ARM for register liveness analysis
* Implement a byte matching heuristic for determining the length of _start
* Implement a spin lock use __atomic_test_and_set on ARM
* 1. Change stop signal from SIGBUS to (SIGRTMIN + 4) in dyninstAPI_RT.
* 2. In dyninstAPI, only do dyninstRT signal check if the signal is indeed
(SIGRTMIN + 4)
* Refacotr BPatch and DyninstRT to use breakpoint as the way of communication
