... as single "internal compiler error" entry point. The macros pass `file!()`, `line!()` and `format_args!(...)` on to a cold, never-inlined function, ultimately calling `bug()` or `span_bug()` on the `Handler` from `session::diagnostic()` via the tcx in tls or, failing that, panicking directly.

librustc: Add bug!(), bug_span!() macros as unified entry points for internal compiler errors
The macros pass `file!()`, `line!()` and `format_args!(...)` on to a cold, never-inlined function, ultimately calling `session::{span_,}bug_fmt` via the tcx in tls or, failing that, panicking directly.
