Auto merge of #123337 - workingjubilee:debug-compiler-profile-expectations, r=fmease
Include line tables in compiler profile This profile has only undergone minimal tweaks since it was originally drafted. I asked a number of compiler contributors and they said they set rust.debug explicitly. This was even true for one contributor that set `rust.debug = false`! Almost everyone seems slightly surprised that `rust.debug = true` is not the default. However, adding full debuginfo at this level costs multiple gigabytes! We can still get much better profiling and such by setting `rust.debuginfo-level = "line-tables-only"` at the cost of only 150~200 MB on the weight of a fresh build dir from `./x.py check`.
