Function sgx_tstd::rt::begin_panic_fmt

pub fn begin_panic_fmt(
    msg: &Arguments, 
    file_line_col: &(&'static str, u32, u32)
) -> !

The entry point for panicking with a formatted message.

This is designed to reduce the amount of code required at the call site as much as possible (so that panic!() has as low an impact on (e.g.) the inlining of other functions as possible), by moving the actual formatting into this shared place.
