When profiling V8 code generated with snapshot using ETW, there is a
huge difference enabling system instrumentation. This is because, for
populating the ETW tracing (when --interpreted-frames-native-stack is
enabled), we need the scripts line ends. But these are only generated if
log functions are enabled.

To prevent the problem, this CL also initializes script line ends for
the case interpreted frames native stacks are enabled.
