Tweak some stabilizations in libstd This commit tweaks a few stable APIs in the `beta` branch before they hit stable. The `str::is_whitespace` and `str::is_alphanumeric` functions were deleted (added in #49381, issue at #49657). The `and_modify` APIs added in #44734 were altered to take a `FnOnce` closure rather than a `FnMut` closure. Closes #49581 Closes #49657

Disable auto-detection of libxml2 when compiling llvm. This broke cross-compiling rustc with internal llvm (with both the host and target being executable on the machine), because llvm's build system detected libxml2 on the host, therefore auto-enabled libxml2 support, but wouldn't compile as the target didn't have libxml2 installed.

wasm: Increase default stack size to 1MB This commit increases the dfeault stack size allocated to the wasm32-unknown-unknown target to 1MB by default. Currently the default stack size is one wasm page, or 64 kilobytes. This default stack is quite small and has caused a stack overflow or two in the wild by accident. The current "best practice" for fixing this is to pass `-Clink-args='-z stack-size=$bigger'` but that's not great nor always easy to do. A default of 1MB matches more closely with other platforms where it's "pretty big" by default. Note that it was tested and if the users uses `-C link-args` to pass a custom stack size that's still resepected as lld seems to take the first argument, and where rustc is passing it will always be last.

Add rustdoc to x.py check Modifying rustc can often cause errors in rustdoc, so it's useful to include it in the steps that are checked. One thing that I was unsure about was when to call `clear_if_dirty` (both in this step, and in other steps in relation to this one) — we want to be sure rustdoc will always be rechecked after modifying previous steps — but does this belong in rustdoc, or the other steps? Fixes #49917. r? @Mark-Simulacrum

Avoid allocating when parsing \u{...} literals. `char_lit` uses an allocation in order to ignore '_' chars in \u{...} literals. This patch changes it to not do that by processing the chars more directly.

proc_macro: Stay on the "use the cache" path more Discovered in #50061 we're falling off the "happy path" of using a stringified token stream more often than we should. This was due to the fact that a user-written token like `0xf` is equality-different from the stringified token of `15` (despite being semantically equivalent). This patch updates the call to `eq_unspanned` with an even more awful solution, `probably_equal_for_proc_macro`, which ignores the value of each token and basically only compares the structure of the token stream, assuming that the AST doesn't change just one token at a time. While this is a step towards fixing #50061 there is still one regression from #49154 which needs to be fixed.

Lazily evaluate EvalErrorKind::*.into() calls. eval_context.rs calls `ok_or` in multiple places with an eagerly evaluated `EvalErrorKind::*.into()` argument, which calls EvalError::from(), which calls env::var("MIRI_BACKTRACE"), which allocates a String. This code is hot enough for this to have a measurable effect on some benchmarks. This patch changes the `ok_or` calls into `ok_or_else`, thus avoiding the evaluations when they're not needed. As a result, most of the rustc-perf benchmarks get a measurable speedup, particularly the shorter-running ones, where the improvement is as high as 6%.

atomic: remove 'Atomic*' from Debug output For the same reason that we don't show `Vec { data: [0, 1, 2, 3] }`, but just the array, the `AtomicUsize(1000)` is noisy, and seeing just `1000` is likely better. -

Add src/test/ui regression testing for NLL This PR changes `x.py test` so that when you are running the `ui` test suite, it will also always run `compiletest` in the new `--compare-mode=nll`, which just double-checks that when running under the experimental NLL mode, the output matches the `<source-name>.nll.stderr` file, if present. In order to reduce the chance of a developer revolt in response to this change, this PR also includes some changes to make the `--compare-mode=nll` more user-friendly: 1. It now generates nll-specific .stamp files, and uses them (so that repeated runs can reuse previously cached results). 2. Each line of terminal output distinguishes whether we are running under `--compare-mode=nll` by printing with the prefix `[ui (nll)]` instead of just the prefix `[ui]`.

Add rustc_trans to x.py check r? @Mark-Simulacrum I looked at `bootstrap/compile.rs` and `bootstrap/check.rs` to try to work out which steps were appropriate, but I'm sure I've overlooked some details here, so it's worth checking carefully I've got all the steps right (e.g. I wasn't sure whether we want to build LLVM if necessary with `x.py check`, though I thought it was probably better to than to not). From a quick test, it seems to be working, though.
