…ering assertion

Issue: <rust-lang#128717>

Parser has error recovery for Unicode-confusables, which includes the
right parentheses `)`. If a multi-byte right parentheses look-alike
reaches the argument removal suggestion diagnostics, it would trigger an
assertion because the diagnostics used `- BytePos(1)` which can land
within a multi-byte codepoint.

This is fixed by using `SourceMap::end_point` to find the final right
delimiter codepoint, which correctly respects codepoint boundaries.

For codepoint boundary assertion triggered by a let stmt compound
assignment removal suggestion when encountering recovered multi-byte
compound ops.

Issue: <rust-lang#128845>

…t codepoint boundaries

Previously we would try to issue a suggestion for `let x <op>= 1`, i.e.
a compound assignment within a `let` binding, to remove the `<op>`. The
suggestion code unfortunately incorrectly assumed that the `<op>` is an
exactly-1-byte ASCII character, but this assumption is incorrect because
we also recover Unicode-confusables like `➖=` as `-=`. In this example,
the suggestion code used a `+ BytePos(1)` to calculate the span of the
`<op>` codepoint that looks like `-` but the mult-byte Unicode
look-alike would cause the suggested removal span to be inside a
multi-byte codepoint boundary, triggering a codepoint boundary
assertion.

This will be useful for certain scenarios where developers want to know
how the tarball sources were generated. We also want this to check for CI
rustc incompatible options on bootstrap.

Add `Steal::is_stolen()`

Writers of rustc drivers (such as myself) often encounter stealing issues. It is currently impossible to gracefully handle them. This PR adds a `Steal::is_stolen()` function for that purpose.

VxWorks code refactored

1. Extern TaskNameSet as minimum supported version of os is VxWorks 7 which would have taskNameSet
2. Vx_TASK_NAME_LEN is 31 on VxWorks7, defined variable res.
3. Add unsafe blocks on Non::Zero usage in available_parallelism()
4. Update vxworks docs.

use stable sort to sort multipart diagnostics

I think a stable sort should be used to sort the different parts of a multipart selection. The current unstable sort uses the text of the suggestion as a tie-breaker. That just doesn't seem right, and the order of the input is a better choice I think, because it gives the diagnostic author more control.

This came up when I was building a suggestion where

```rust
fn foo() {}
```

must be turned into an unsafe function, and an attribute must be added

```rust
#[target_feature(enable = "...")]
unsafe fn foo() {}
```

In this example, the two suggestions occur at the same position, but the order is extremely important: unsafe must come after the attribute. But the situation changes if there is a pub/pub(crate), and if the unsafe is already present. It just out that because of the suggestion text, there is no way for me to order the suggestions correctly.

This change probably should be tested, but are there tests of the diagnostics code itself in the tests?

Use `SourceMap::end_point` instead of `- BytePos(1)` in arg removal suggestion

Previously, we tried to remove extra arg commas when providing extra arg removal suggestions. One of
the edge cases is having to account for an arg that has a closing delimiter `)` following it.
However, the previous suggestion code assumed that the delimiter is in fact exactly the 1-byte `)`
character. This assumption was proven incorrect, because we recover from Unicode-confusable
delimiters in the parser, which means that the ending delimiter could be a multi-byte codepoint
that looks *like* a `)`. Subtracing 1 byte could land us in the middle of a codepoint, triggering a
codepoint boundary assertion.

This is fixed by using `SourceMap::end_point` which properly accounts for codepoint boundaries.

Fixes rust-lang#128717.

Ensure let stmt compound assignment removal suggestion respect codepoint boundaries

Previously we would try to issue a suggestion for `let x <op>= 1`, i.e.
a compound assignment within a `let` binding, to remove the `<op>`. The
suggestion code unfortunately incorrectly assumed that the `<op>` is an
exactly-1-byte ASCII character, but this assumption is incorrect because
we also recover Unicode-confusables like `➖=` as `-=`. In this example,
the suggestion code used a `+ BytePos(1)` to calculate the span of the
`<op>` codepoint that looks like `-` but the mult-byte Unicode
look-alike would cause the suggested removal span to be inside a
multi-byte codepoint boundary, triggering a codepoint boundary
assertion.

The fix is to use `SourceMap::start_point(token_span)` which properly accounts for codepoint boundaries.

Fixes rust-lang#128845.

Disable verbose bootstrap command failure logging by default

One of my recent bootstrap command refactoring PRs enabled verbose logging of command failures by default. While this is great for debugging bootstrap, in many situations it's just too verbose and prevents the user from seeing the actual printed stdout/stderr, which usually contains much more useful information.

This PR reverts that logic, and only prints a detailed error when `-v` is passed to bootstrap.
