Enable LVI hardening for x86_64-fortanix-unknown-sgx
This implements mitigations for the Load Value Injection vulnerability (CVE-2020-0551) for the `x86_64-fortanix-unknown-sgx` target by enabling new LLVM passes. More information about LVI and mitigations may be found at https://software.intel.com/security-software-guidance/insights/deep-dive-load-value-injection.
This PR unconditionally enables the mitigations for `x86_64-fortanix-unknown-sgx` since there is no available hardware that doesn't require the mitigations. This may be reconsidered in the future.
* [x] This depends on https://github.com/rust-lang/compiler-builtins/pull/359/
Update annotate-snippets-rs to 0.8.0
#59346
I made major changes to this library. In the previous version we worked with owned while in the current one with borrowed.
I have adapted it without changing the behavior.
I have modified the coverage since the previous one did not return correctly the index of the character in the line.
Recursively expand `TokenKind::Interpolated` in `probably_equal_for_proc_macro`
Fixes#68430
When comparing the captured and re-parsed `TokenStream` for a `TokenKind::Interpolated`, we currently treat any nested `TokenKind::Interpolated` tokens as unequal. If a `TokenKind::Interpolated` token shows up in the captured `TokenStream` due to a `macro_rules!` expansion, we will throw away the captured `TokenStream`, losing span information.
This PR recursively invokes `nt_to_tokenstream` on nested `TokenKind::Interpolated` tokens, effectively flattening the stream into a sequence of non-interpolated tokens. This allows it to compare equal with the re-parsed stream, allowing us to keep the original captured `TokenStream` (with span information).
This requires all of the `probably_equal_for_proc_macro` methods to be moved from `librustc_ast` to `librustc_parse` so that they can call `nt_to_tokenstream`.

update stacker to 0.1.9 to unbreak build on OpenBSD
the version 0.1.8 of stacker (what is currently pinned in Cargo.lock) doesn't build on OpenBSD (see https://github.com/rust-lang/stacker/pull/34).
update the version to 0.1.9
