the constant is wrong on some platforms (e.g., on mips64el it's 0x10, and 0x8
is RTLD_NOLOAD which makes all this functionality broken), the libc crate takes
care of those differences for us.
fallback to not setting the flag in non-glibc environments - some of them might
have support for it using a different value that we don't know about, and some
of them lack it entirely.

Improve `select_nth_unstable` documentation clarity
* Instead uses `before` and `after` variable names in the example
where `greater` and `lesser` are flipped.
* Uses `<=` and `>=` instead of "less than or equal to" and "greater
than or equal to" to make the docs more concise.
* General attempt to remove unnecessary words and be more precise. For
example it seems slightly wrong to say "its final sorted position",
since this implies there is only one sorted position for this element.
Stable Hash: Ignore all HirIds that just identify the node itself
This should provide better incremental caching, but it seems there is more to it.
These IDs also serve no purpose being in the stable hash of the item they refer to, only when referring to *another* item is it important that we hash the `HirId`. So we can at least avoid the cost during stable hashing, even if we don't benefit from it by avoiding some queries' caches from being invalidated
Unsure how to make sure we do this right by construction. Would be nice to do something type based
Add gpu-kernel calling convention
The amdgpu-kernel calling convention was reverted in commit f6b21e90d1ec01081bc2619efb68af6788a63d65 (#120495 and https://github.com/rust-lang/rust-analyzer/pull/16463) due to inactivity in the amdgpu target.
Introduce a `gpu-kernel` calling convention that translates to `ptx_kernel` or `amdgpu_kernel`, depending on the target that rust compiles for.
Tracking issue: #135467
amdgpu target tracking issue: #135024
Use trait definition cycle detection for trait alias definitions, too
fixes#133901
In general doing this for `All` is not right, but this code path is specifically for traits and trait aliases, and there we only ever use `All` for trait aliases.
