Fix cargo tests when running inside the rustlang/rust repo
It seems we hit https://github.com/rust-lang/cargo/issues/5418, so I've applied the suggested solution. Also added some more info when cargo-metadata fails to execute.

resolve: Sort E0408 errors by Symbol str
This is a request for comments implementing my suggested solution to https://github.com/rust-lang/rust/issues/72913
Previously errors were sorted by Symbol index instead of the string. The indexes are not the same between architectures because Symbols for architecture extensions (e.g. x86 AVX or RISC-V d) are interned before the source file is parsed. RISC-V's naming of extensions after single letters led to it having errors sorted differently for test cases using single letter variable names. Instead sort the errors by the Symbol string so that it is stable across architectures.
While I was at it, there's also 8edb05c2 skipping some ui tests which I think are irrelevant for risc-v.
This commit removes the `#[cfg]` guards in `atomic::fence` on wasm
targets. Since these guards were originally added the upstream wasm
specification for threads gained an `atomic.fence` instruction, so LLVM
no longer panics on these intrinsics.
Although there aren't a ton of tests in-repo for this right now I've
tested locally and all of these fences generate `atomic.fence`
instructions in wasm.

Fixes#72839
In PR #72621, trait selection was modified to no longer bail out early
when an error type was encountered. This allowed us treat `ty::Error` as
`Sized`, causing us to avoid emitting a spurious "not sized" error after
a type error had already occured.
However, this means that we may now try to match an impl candidate
against the error type. Since the error type will unify with almost
anything, this can cause us to infinitely recurse (eventually triggering
an overflow) when trying to verify certain `where` clauses.
This commit causes us to skip generating any impl candidates when an
error type is involved.
Currently, the `Debug` impl for `proc_macro::Span` just prints out
the byte range. This can make debugging proc macros (either as a crate
author or as a compiler developer) very frustrating, since neither the
actual filename nor the `SyntaxContext` is displayed.
This commit adds a perma-unstable flag `-Z span-debug`. When enabled,
the `Debug` impl for `proc_macro::Span` simply forwards directly to
`rustc_span::Span`. Once #72618 is merged, this will start displaying
actual line numbers.
While `Debug` impls are not subject to Rust's normal stability
guarnatees, we probably shouldn't expose any additional information on
stable until `#![feature(proc_macro_span)]` is stabilized. Otherwise,
we would be providing a 'backdoor' way to access information that's
supposed be behind unstable APIs.
Add myself to mailmap
Now that I have (accidentally) made contributions using two separate email addresses, I've added the rest of the addresses I typical use.
Add more assert to Vec with_capacity docs
Show assertion on len too to show them how adding new items will affect both the
length and capacity, before and after.
We were computing a merge-base between the remote beta and master
branches, but this was giving incorrect answers for the first beta if
the remote hadn't been pushed yet. For instance, `1.45.0-beta.3359`
corresponds to the number of merges since the 1.44 beta, but we really
want just `.1` for the sole 1.45 beta promotion merge.
We don't really need to query the remote beta at all -- `master..HEAD`
suffices if we assume that we're on the intended beta branch already.
