Currently, there are many places in rustc, where we use
with_freevars to iterate over freevars of a closure. The
problem with this is the argument to with_freevars is a
NodeId and this will get in the way of our eventual goal
of solving for issue (#53488), sub-issue (#56905)
Adding a map to TypeckTables to get the list of all the Upvars
given a closureID. This is help us get rid of the recurring
pattern in the codebase of iterating over the free vars
using with_freevars.
Remove some `Region`s from HAIR
Use `ReErased` for any regions that need to be created in RValue::Ref
in MIR generation. We will change them to all to `ReVar` before borrow
checking anyway.

Build LLVM with -static-libstdc++ on dist builds
This commit is intended on fixing a regression from #57286 where the
distributed LLVM shared library unfortunately depends on a dynamic copy
of libstdc++, meaning we're no longer as binary compatible as we
thought! This tweaks the build of LLVM as out distribution is slightly
different now, and is hoped to fix the issue.
Closes#57426
std: Force `Instant::now()` to be monotonic
This commit is an attempt to force `Instant::now` to be monotonic
through any means possible. We tried relying on OS/hardware/clock
implementations, but those seem buggy enough that we can't rely on them
in practice. This commit implements the same hammer Firefox recently
implemented (noted in #56612) which is to just keep whatever the lastest
`Instant::now()` return value was in memory, returning that instead of
the OS looks like it's moving backwards.

`TokenStream` is currently recursive in *two* ways:
- the `TokenTree` variant contains a `ThinTokenStream`, which can
contain a `TokenStream`;
- the `TokenStream` variant contains a `Vec<TokenStream>`.
The latter is not necessary and causes significant complexity. This
commit replaces it with the simpler `Vec<(TokenTree, IsJoint)>`.
This reduces complexity significantly. In particular, `StreamCursor` is
eliminated, and `Cursor` becomes much simpler, consisting now of just a
`TokenStream` and an index.
The commit also removes the `Extend` impl for `TokenStream`, because it
is only used in tests. (The commit also removes those tests.)
Overall, the commit reduces the number of lines of code by almost 200.
