Also change Memory::copy to work on `Pointer` instead of `Scalar`.
Also rename some methods from to_* to assert_* that will panic if their precondition is not met.
The auxiliary file arc_wake.rs is in run-pass/auxiliary and also
ui/async-await/auxiliary. Remove the former one as their contents
are same.
Move run-pass/futures-api.rs to ui/async-await/futures-api.rs as it
needs to use arc_wake.rs.

Remove support for 1-token lookahead from the lexer
`StringReader` maintained `peek_token` and `peek_span_src_raw` for look ahead.
`peek_token` was used only by rustdoc syntax coloring. After moving peeking logic into highlighter, I was able to remove `peek_token` from the lexer. I tried to use `iter::Peekable`, but that wasn't as pretty as I hoped, due to buffered fatal errors. So I went with hand-rolled peeking.
After that I've noticed that the only peeking behavior left was for raw tokens to test tt jointness. I've rewritten it in terms of trivia tokens, and not just spans.
After that it became possible to simplify the awkward constructor of the lexer, which could return `Err` if the first peeked token contained error.
Fix perf regression from Miri Machine trait changes
Maybe this fixes the perf regression that https://github.com/rust-lang/rust/pull/62003 seemingly introduced?

forward read_c_str method from Memory to Alloc
This is more convenient to call when one starts with a `Scalar` (which is the common case).
`read_c_str` is only used in Miri.
Miri engine: support extra function (pointer) values
We want to add basic support for `dlsym` in Miri (needed to run the latest version of `getrandom`). For that to work, `dlsym` needs to return *something* that can be stored in a function pointer and later called.
So we add a new `ExtraFnVal` type to the `Machine` trait, and enable Miri's memory to associate allocation IDs with such values, so that `create_fn_alloc` and `get_fn` can work on *both* `Instance` (this is used for "normal" function pointers) and `ExtraFnVal`.

Update linked OpenSSL version
This bumps our linked OpenSSL version from 1.1.1a to 1.1.1c, picking up
some various bug fixes and minor security issue fixes.
Lint on invalid values passed to x.py --warnings
This also introduces support for `--warnings allow` and fixes --warnings
being overridden by the configuration file, config.toml.
Fixes#62402

remove Scalar::is_null_ptr
Comparing pointers should be done more carefully than that. With https://github.com/rust-lang/miri/pull/825, Miri does not need it any more and it is otherwise unused.
rustc_target: avoid negative register counts in the SysV x86_64 ABI.
Because `needed_{int,sse}` and `{int,sse}_regs` were only used with integer literals, they were inferred to `i32` and `{int,sse}_regs` could therefore be negative.
There was a check which prevented that, but *only* for aggregate arguments, not scalars.
Fixes#62350.

Remove `compile-pass` from compiletest
This is a part of #62277.
Removes `compile-pass` from compiletest (and modify some tests' annotations).

Create async version of the dynamic-drop test
Some of the tests in dynamic-drop have been cut:
* The tests that are just simpler versions of other tests - these tests are already fairly slow due to all of the unwinding and async functions have more control flow paths than normal functions.
* The union test - it's for an unstable feature that has an RFC to remove it.
* The generator test - there aren't async generators yet.
* The tests that show values being leaked - these can be added once the issue is fixed.
