RFR(XXS) 8201242: Include source file/line number when reporting native call stack on supported platforms

[Daniel D. Daugherty]

Hi Zhengyu,

Okay, I'm less confused now than when this bug first came in this AM...
This fix is for NMT (which I sort of guessed because it's you :-)).
I've been recently playing with VM_Error::print_native_stack() and
I know that code includes the source file/line number...
