This fixes the changes brought to codegen tests when effect params are
added to libcore, by not attempting to monomorphize functions that get
the host param by being `const fn`.
some inspect improvements
split from #114810 because I still want to experiment a bunch with that PR and these changes are self-contained.
r? `@compiler-errors`
Rework `no_coverage` to `coverage(off)`
As discussed at the tail of https://github.com/rust-lang/rust/issues/84605 this replaces the `no_coverage` attribute with a `coverage` attribute that takes sub-parameters (currently `off` and `on`) to control the coverage instrumentation.
Allows future-proofing for things like `coverage(off, reason="Tested live", issue="#12345")` or similar.

Disabled socketpair for Vita
There is no `socketpair` syscall in Vita newlib. This is reflected in a rust-lang/libc#3284, in which this method is removed for vita target.
Also, we would need the fixes from the abovementioned PR for sockets in std (previously we had some incorrect constant values), but that can be done separately when rust-lang/libc#3284 is reviewed, merged, and released.
Merge settings.css into rustdoc.css
There aren't that many CSS rules in `settings.css`, however quite some code is needed around it, making it more costly than useful. I think it's better to merge into `rustdoc.css` to simplify this.
r? `@notriddle`
cleanup leftovers of const_err lint
Some code / comments seem to not have been updated when const_err was turned into a hard error, so we can do a bit of cleanup here.
r? `@oli-obk`
Remove `verbose_generic_activity_with_arg`
This removes `verbose_generic_activity_with_arg` and changes users to `generic_activity_with_arg`. This keeps the output of `-Z time` readable while these repeated events are still available with the self profiling mechanism.
- Add doc comment to new type
- Restore "only supported directly in conditions of `if` and `while` expressions" note
- Rename variant with clearer name
Make compiletest output truncation less disruptive
When the test output becomes too large, compiletest stops recording all of it. However:
- this can lead to invalid JSON, which then causes compiletest itself to throw further errors
- the note that output was truncated is in the middle of the output, with >100kb of text on each side; that makes it almost impossible to actually see that note in the terminal
So assuming that we do need to keep the output truncation, I propose that we only ever do a cut at the end, so that it is very clear by looking at the end of the log that truncation happened. I added a message at the beginning of the output as well. Also I added some logic to make it less likely that we'll cut things off in the middle of a JSON record. (I tested that successfully by reducing the output limit to something very low and running a few ui tests.) Furthermore I increased the max buffer size to 512KB; that's really not a lot of memory compared to how much RAM it takes to build rustc (it's ~25% more than the previous maximum HEAD+TAIL length). And finally, the information that things got truncated is now propagated to the higher levels, so that we can fail the test instead of comparing the truncated output with the reference.
