fix typo in note about multiple inaccessible type aliases
Mainly intended as a small typo fix ("aliass" -> "aliases") for the case where a type cannot be found in scope but there are multiple inaccessible type aliases that match the missing type.
In general this change would use the correct plural form in this scenario for base words that end with 's'.
macros: `LintDiagnostic` derive
- Move `LintDiagnosticBuilder` into `rustc_errors` so that a diagnostic derive can refer to it.
- Introduce a `DecorateLint` trait, which is equivalent to `SessionDiagnostic` or `AddToDiagnostic` but for lints. Necessary without making more changes to the lint infrastructure as `DecorateLint` takes a `LintDiagnosticBuilder` and re-uses all of the existing logic for determining what type of diagnostic a lint should be emitted as (e.g. error/warning).
- Various refactorings of the diagnostic derive machinery (extracting `build_field_mapping` helper and moving `sess` field out of the `DiagnosticDeriveBuilder`).
- Introduce a `LintDiagnostic` derive macro that works almost exactly like the `SessionDiagnostic` derive macro except that it derives a `DecorateLint` implementation instead. A new derive is necessary for this because `SessionDiagnostic` is intended for when the generated code creates the diagnostic. `AddToDiagnostic` could have been used but it would have required more changes to the lint machinery.

Proper macOS libLLVM symlink when cross compiling
Follow up of #98418
When cross compiling on macOS with `llvm.link-shared` enabled, the symlink creation will fail after compiling LLVM for the target architecture, because it will attempt to create the symlink in the host LLVM directory, which was already created when being built.
This commit changes the symlink path to the actual LLVM output.

Fix repr(align) enum handling
`enum`, for better or worse, supports `repr(align)`. That has already caused a bug in https://github.com/rust-lang/rust/issues/92464, which was "fixed" in https://github.com/rust-lang/rust/pull/92932, but it turns out that that fix is wrong and caused https://github.com/rust-lang/rust/issues/96185.
So this reverts #92932 (which fixes#96185), and attempts another strategy for fixing #92464: special-case enums when doing a cast, re-using the code to load the discriminant rather than assuming that the enum has scalar layout. This works fine for the interpreter.
However, #92464 contained another testcase that was previously not in the test suite -- and after adding it, it ICEs again. This is not surprising; codegen needs the same patch that I did in the interpreter. Probably this has to happen [around here](d32ce37a17/compiler/rustc_codegen_ssa/src/mir/rvalue.rs (L276)). Unfortunately I don't know how to do that -- the interpreter can load a discriminant from an operand, but codegen can only do that from a place. `@oli-obk` `@eddyb` `@bjorn3` any idea?
bootstrap: Allow building individual crates
This aims to be as unintrusive as possible, but did still require adding a new `tail_args` field to all `Rustc` and `Std` steps.
New library and compiler crates are added to the sysroot as they are built, since it's useful to have e.g. just alloc and not std.
Fixes https://github.com/rust-lang/rust/issues/44293.
adapt issue-37945 codegen test to accept any order of ops
Adapt this test to accept `icmp` operands in any order as a follow-up to cbbf06b0cd (commitcomment-77670922).
bootstrap.py: Always use `.exe` for Windows
This ensures that it will run the Windows executable if other files in the directory (such as Linux executables) have the same file name minus the extension. I've been tripped up by this a few times where both `bootstrap` and `bootstrap.exe` end up in the same directory.
This PR avoids ever having to see the following message:
`OSError: [WinError 193] %1 is not a valid Win32 application`
