This is a follow-up to r364466, but better implemented. Original
commit message still applies:
The breakpoint locations were in places where clang doesn't actually
emit a source location for and depend on the debugger's ability to
move the breakpoint forward onto a line that is already in the
function epilogue. In my testing older versions of LLDB fail to do
that, so I'm modifying the test to force a break-able location by
calling a noinline function.
