Adds --bless support to test/run-make-fulldeps
The ability to "bless" output for some of these tests is critical to
making it practical to adapt tests to unrelated changes.
This is needed for new coverage tests, as shown in PR #76004 .

Add InstrProfilingPlatformFuchsia.c to profiler_builtins
All other Platform files included in `llvm-project/compiler-rt` were
present, except Fuchsia.
Now that there is a functional end-to-end version of
`-Zinstrument-coverage`, I need to start building and testing
coverage-enabled Rust programs on Fuchsia, and this file is required.

Rename rustdoc/test -> rustdoc/doctest
This modules contains the implementation of doctests, and not the
tests of rustdoc itself. This name is confusing, so let's rename it to
doctest for clarity.
Fix potential UB in align_offset doc examples
Currently it takes a pointer only to the first element in the array, this changes the code to take a pointer to the whole array.
miri can't catch this right now because it later calls `x.len()` which re-tags the pointer for the whole array.

Abort when foreign exceptions are caught by catch_unwind
Prior to this PR, foreign exceptions were not caught by catch_unwind, and instead passed through invisibly. This represented a painful soundness hole in some libraries ([take_mut](https://github.com/Sgeo/take_mut/blob/master/src/lib.rs#L37)), which relied on `catch_unwind` to handle all possible exit paths from a closure.
With this PR, foreign exceptions are now caught by `catch_unwind` and will trigger an abort since catching foreign exceptions is currently UB according to the latest proposals by the FFI unwind project group.

Fix FP in `to_string_in_display`
Don't emit a lint when `.to_string()` on anything that is not `self`
Fix#5967
changelog: Fix FP in `to_string_in_display` when calling `.to_string()` on anything that is not `self`
Disable cancel-outdated-builds for auto-fallible
`cancel-outdated-builds` doesn't need to be enabled on fallible jobs, and it's actually making it harder for us to see if https://github.com/rust-lang/rust/issues/71988 is fixed. This adds some temporary code to avoid `auto-fallible` jobs from being cancelled by our tooling.

Improve help popup
Fixes#75623.
The second commit is just a slight improvement: the help popup won't be created until someone presses "?" or ESC. Not a big improvement in itself but considering the low amount of code required, I think it was worth the shot.
