On macOS, it's not yet clear which cases of clang/OS/target/SDK version impact
how to find ld/lld/rust-lld. The --target is not needed on our current targets with
a vanilla config, but may be in some cases. Specifying it all the time breaks the 10.7+
targets on x64 macOS.
We try to only specify it on macOS if the linker flavors are different,
for possible cases of cross-compilation with `-Zgcc-ld=lld` but the
expectation is that it should be passed manually when needed in these
situations.
This allows analyzing the output programatically; for example, finding
the item with the highest `total_estimate`.
I also took the liberty of adding `untracked` tests to `rustc_session` and documentation to the unstable book for `dump-mono-items`.
Reenable limited top-down MIR inlining
Reverts most of #105119 and uses an alternative strategy to prevent exponential blowup. Specifically, we allow doing top-down inlining up to depth at most five, and for at most one call site per nested body.

chore: fix identation of `if_chain` in `filter_map`
This is a really small fix.
If someone could take a look at it, I would appreciate it🙏

[current Firefox ESR] is version 102.
* The last version of Safari that required a vendor prefix was version 5.
The current version is 16.
* The last version of Safari/iOS that required a vendor prefix was version 4.
The current version is 16.

Abolish `QueryVTable` in favour of more assoc items on `QueryConfig`
This may introduce additional mono _but_ may help const fold things better and especially may help not constructing a `QueryVTable` anymore which is cheap but not free.

HIR debug output is currently very verbose, especially when used with
the alternate (`#`) flag. This commit reduces the amount of noisy
newlines by forcing a few small key types to stay on one line, which
makes the output easier to read and scroll by.

Context is no longer Sync so this doesn't work.
