overhaul exit codes for rustc and rustdoc This commit changes the exit status of rustc to 1 in the presence of compilation errors. In the event of an unexpected panic (ICE) the standard panic error exit status of 101 remains. A run-make test is added to ensure that the exit code does not regress, and compiletest is updated to check for an exit status of 1 or 101, depending on the mode and suite. This is a breaking change for custom drivers. Note that while changes were made to the rustdoc binary, there is no intended behavior change. rustdoc errors (i.e., failed lints) will still report 101. While this could *also* hide potential ICEs, I will leave that work to a future PR. Fixes #51971. |

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 guide.
