This commit adjusts MIR shim construction so that substitutions are applied to function pointer shims during construction, rather than during codegen (as determined by `substs_for_mir_body`) - as substitutions will no longer occur during codegen, function pointer shims can now be polymorphic without incurring double substitutions.

glibc destroys[1] the passed pthread_attr_t if pthread_getattr_np() fails. Destroying it again leads to a segfault. Fix it by only destroying it on success for glibc. [1]: https://sourceware.org/git/?p=glibc.git;a=blob;f=nptl/pthread_getattr_np.c;h=ce437205e41dc05653e435f6188768cccdd91c99;hb=HEAD#l205
…ibcs The calling convention of pthread_getattr_np() is to initialize the pthread_attr_t, so _destroy() is only necessary on success (and _init() isn't necessary beforehand). On the other hand, FreeBSD wants the attr_t to be initialized before pthread_attr_get_np(), and therefore it should always be destroyed afterwards.
Make the following methods unstable const under the `const_pin` feature: - `new` - `new_unchecked` - `into_inner` - `into_inner_unchecked` - `get_ref` - `into_ref` Also adds tests for these methods in a const context. Tracking issue: rust-lang#76654
Only insert StorageDeads if we actually removed one. Fixes an issue where we added StorageDead to a place with no StorageLive
This is heavily dependent on MIR inlining running to actually see the drop statement

A significant amount of intrinsics do not actually need backend-specific behaviors to be implemented, instead relying on methods already in rustc_codegen_ssa. So, extract those methods out to rustc_codegen_ssa, so that each backend doesn't need to reimplement the same code.
Use `SyncOnceCell` to only compile it once. I believe this still adds some kind of locking mechanism?
The use of arith_offset was added in 803e9ae before the stable wrapper of the intrinsic was available. https://doc.rust-lang.org/stable/std/intrinsics/fn.arith_offset.html
The latter is on the path to stabilization.

This moves build triple discovery for rustbuild from bootstrap.py into a build script, meaning it will "just work" if building rustbuild via Cargo rather than Python.
This requires that bootstrap is run from the same worktree as the sources it'll build, but this is basically required for the build to work anyway. You can still run it from a different directory, just that the files it builds must be beside it.
Only get ImplKind::Impl once With this, the code panics in one place instead of two.

…ures, r=oli-obk,Mark-Simulacrum Remove redundant nightly features Removes a bunch of redundant/outdated nightly features. The first commit removes a `core_intrinsics` use for which a stable wrapper has been provided since. The second commit replaces the `const_generics` feature with `min_const_generics` which might get stabilized this year. The third commit is the result of a trial/error run of removing every single feature and then adding it back if compile failed. A bunch of unused features are the result that the third commit removes.

use `array_windows` instead of `windows` in the compiler I do think these changes are beautiful, but do have to admit that using type inference for the window length can easily be confusing. This seems like a general issue with const generics, where inferring constants adds an additional complexity which users have to learn and keep in mind.
