[llvm] r219558 - Guard the definition of the stack tracing function with the same macros

New Revision: 219558

URL: http://llvm.org/viewvc/llvm-project?rev=219558&view=rev
Log:
Guard the definition of the stack tracing function with the same macros
that guard its usage. Without this, we can get unused function warnings
when backtraces are disabled.
