Make rustc use `RUST_BACKTRACE=full` by default Compiler panics should be rare - when they do occur, we want the report filed by the user to contain as much information as possible. This is especially important when the panic is due to an incremental compilation bug, since we may not have enough information to reproduce it. This PR sets `RUST_BACKTRACE=full` inside `rustc` if the user has not explicitly set `RUST_BACKTRACE`. This is more verbose than `RUST_BACKTRACE=1`, but this may make it easier to debug incremental compilation issues. Users who find this too verbose can still manually set `RUST_BACKTRACE` before invoking the compiler. This only affects `rustc` (and any tool using `rustc_driver::install_ice_hook`). It does *not* affect any user crates or the standard library - backtraces will continue to be off by default in any application *compiled* by rustc.

error[E0425]: cannot find value `missing_ident` in this scope
Improve filtering in `default-backtrace-ice.rs`. This test is supposed to ensure that full backtraces are used for ICEs. But it doesn't actually do that -- the filtering done cannot distinguish between a full backtrace versus a short backtrace. So this commit changes the filtering to preserve the existence of `__rust_{begin,end}_short_backtrace` markers, which only appear in full backtraces. This change means the test now tests what it is supposed to test. Also, the existing filtering included a rule that excluded any line starting with two spaces. This was too strong because it filtered out some parts of the error message. (This was not a showstopper). It was also not strong enough because it didn't work with three digit stack frame numbers, which just started seeing after upgrading my Ubuntu distro to 23.04 machine (this *was* a showstopper). So the commit replaces that rule with two more precise rules, one for lines with stack frame numbers, and one for "at ..." lines.
