gdb singlestep tracing annotated with registry content and basic block numbers

the crash happens when the code takes the execution path
bb5 -> bb0 -> bb1 -> bb3 -> bb5 -> bb0 (crash)

smells like llvm codegen bug that llvm forgets to backup lr when calling bb0
from bb5 so that bb5 return to bb0 instead of bb2
