Add target and compile the amdgpu llvm backend.
only MUSL needs those objects and trying to compile them to other
targets, e.g. Windows or macOS, will produce C compilation errors

check the target before shelling out to the C compiler and tweak
`make_run` to skip the actual C compilation when the target is not MUSL

fixes rust-lang#135782
Provide a new function `listify`, meant to be used in cases similar to `pluralize!`. When you have a slice of arbitrary elements that need to be presented to the user, `listify` allows you to turn that into a list of comma separated strings.

This reduces a lot of redundant logic that happens often in diagnostics.
Make it so more type-system types can be printed in a shortened version (like `Predicate`s).

Centralize printing the information about the "full type name path".

Make the "long type path" for the file where long types are written part of `Diag`, so that it becomes easier to keep track of it, and ensure it will always will be printed out last in the diagnostic by making its addition to the output implicit.

Tweak the shortening of types in "expected/found" labels.

Remove dead file `note.rs`.

Add amdgpu target

Add amdgpu target to rustc and enable the LLVM target.

Fix compiling `core` with the amdgpu:
The amdgpu backend makes heavy use of different address spaces. This
leads to situations, where a pointer in one addrspace needs to be casted
to a pointer in a different addrspace. `bitcast` is invalid for this
case, `addrspacecast` needs to be used.

Fix compilation failures that created bitcasts for such cases by
creating pointer casts (which creates an `addrspacecast` under the hood)
instead.

MCP: rust-lang/compiler-team#823
Tracking issue: rust-lang#135024
Kinda related to the original amdgpu tracking issue rust-lang#51575 (though that one has been closed for a while).

bootstrap: only build `crt{begin,end}.o` when compiling to MUSL

only MUSL needs those objects and trying to compile them to other targets, e.g. Windows or macOS, will produce C compilation errors

check the target before shelling out to the C compiler and tweak `make_run` to skip the actual C compilation when the target is not MUSL

Rename `tcx.ensure()` to `tcx.ensure_ok()`, and improve the associated docs

This is all based on my archaeology for https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/.60TyCtxtEnsure.60.

The main renamings are:
- `tcx.ensure()` → `tcx.ensure_ok()`
- `tcx.ensure_with_value()` → `tcx.ensure_done()`
- Query modifier `ensure_forwards_result_if_red` → `return_result_from_ensure_ok`

Hopefully these new names are a better fit for the *actual* function and purpose of these query call modes.
Update encode_utf16 to mention it is native endian

Rework "long type names" printing logic

Make it so more type-system types can be printed in a shortened version (like `Predicate`s).

Centralize printing the information about the "full type name path".

Make the "long type path" for the file where long types are written part of `Diag`, so that it becomes easier to keep track of it, and ensure it will always will be printed out last in the diagnostic by making its addition to the output implicit.

Tweak the shortening of types in "expected/found" labels.

CompileTest: Add Directives to Ignore `arm-unknown-*` Targets

In  rust-lang#134626, I want to ignore `arm-unknown-*` targets because the LLVM IR for those looks very different compared to other targets: https://rust.godbolt.org/z/ssYMhdv4x.

I can use `ignore-arm` but, I think, it would exclude large number of Apple devices.

So this PR adds a few directives to ignore `arm-unknown-*` targets specifically.

Make comma separated lists of anything easier to make for errors

Provide a new function `listify`, meant to be used in cases similar to `pluralize!`. When you have a slice of arbitrary elements that need to be presented to the user, `listify` allows you to turn that into a list of comma separated strings.

This reduces a lot of redundant logic that happens often in diagnostics.
