when running `tests/ui/panics/default-backtrace-ice.rs locally it gave this error: ``` failures: ---- [ui] tests/ui/panics/default-backtrace-ice.rs stdout ---- Saved the actual stderr to "/home/jyn/src/rust3/build/x86_64-unknown-linux-gnu/test/ui/panics/default-backtrace-ice/default-backtrace-ice.stderr" diff of stderr: 7 8 aborting due to `-Z treat-err-as-bug=1` 9 stack backtrace: - (end_short_backtrace) - (begin_short_backtrace) - (end_short_backtrace) - (begin_short_backtrace) + [... omitted 22 frames ...] + ``` this is a regression from setting RUST_BACKTRACE=1 by default. we need to turn off the new behavior when running UI tests so that they reflect our dist compiler. normally that's done by checking `sess.unstable_opts.ui_testing`, but this happens extremely early in the compiler before we've expanded arg files. do an extremely simple hack that doesn't work in all cases - we don't need it to work in all cases, only when running UI tests. |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
