this pr add some statement about intending to provide `Termination` trait only on standard library's runtime.

Suggest constraining param for unary ops when missing trait impl
This PR adds a suggestion of constraining param for unary ops `-` and `!` when the corresponding trait implementation
is missing.
Fixs #94543.
BTW, this is my first time to touch rustc, please correct me if I did anything wrong.
rename LocalState::Uninitialized to Unallocated
This is to avoid confusion with `Uninit` as in `ScalarMaybeUninit`, which is very different.

Inline some parser functions
Some crates that do a lot of complex declarative macro expansion spend a lot of time parsing (and reparsing) tokens. These commits inline some functions for some minor speed wins.

Preserve the Windows `GetLastError` error in `HandleOrInvalid`.
In the `TryFrom<HandleOrInvalid> for OwnedHandle` and
`TryFrom<HandleOrNull> for OwnedHandle` implemenations, `forget` the
owned handle on the error path, to avoid calling `CloseHandle` on an
invalid handle. It's harmless, except that it may overwrite the
thread's `GetLastError` error.

Disable almost certainly unsound early otherwise branch MIR opt
Originally thought this was just an MIR semantics issue, but it's not.
r? rust-lang/mir-opt
The call site within `Parser::bump` is hot.
Also add an inline annotation to `Parser::next_tok`. It was already
being inlined by the compiler; this just makes sure that continues.

Return err instead of ICE
Having `escaping_bound_vars` results in ICE when trying to create `ty::Binder::dummy`, to avoid it we return err like the line above. I think this requires a more sophisticated fix, I would love to investigate if mentorship is available 🤓Fixes#95023 and #85350
Don't run UB in test suite
This splits `ui/unsafe/union.rs` to make it so only the non-UB parts are run. It also means we can do more testing of the location of error messages (which are a bit different with the THIR unsafety checker). `union-modification.rs` has no UB (according to Miri), and `union.rs` has errors (but would have UB if not for those errors).
Closes#95075.

suggest removing type ascription in bad parsing position
Not sure how to test this with the non-nightly suggestion. Didn't add a new UI test because it already manifests in an existing UI test.

Skip a test if symlink creation is not possible
If someone running tests on Windows does not have Developer Mode enabled then creating symlinks will fail which in turn would cause this test to fail. This can be a stumbling block for contributors.
