6f93e93af6 Auto merge of #55947 - michaelwoerister:xlto-fix-lld-opt, r=Mark-Simulacrum 
xLTO: Don't pass --plugin-opt=thin to LLD. That's not supported anymore.

It seems that `-plugin-opt=thin` is not needed anymore when invoking LLD for ThinLTO. Unfortunately, still passing the option makes LLD crash instead of giving a deprecation warning or something.

Switch AppVeyor builds to the GCE cloud

[Recommended by AppVeyor][1] this isn't done by default for all builds
due to the high startup overhead (3-4 minutes for a VM), but that's
paltry compared to our overall build times so should be more than
applicable!

9fefb67669 Auto merge of #55356 - Aaron1011:fix/rustdoc-negative-auto, r=nikomatsakis 
Check for negative impls when finding auto traits

Fixes #55321

When AutoTraitFinder begins examining a type, it checks for an explicit
negative impl. However, it wasn't checking for negative impls found when
calling 'select' on predicates found from nested obligations.

This commit makes AutoTraitFinder check for negative impls whenever it
makes a call to 'select'. If a negative impl is found, it immediately
bails out.

Normal users of SelectioContext don't need to worry about this, since
they stop as soon as an Unimplemented error is encountered. However, we
add predicates to our ParamEnv when we encounter this error, so we need
to handle negative impls specially (so that we don't try adding them to
our ParamEnv).
