Implementation of rust-lang/libs-team#367. This mainly adds `BorrowedCursor::with_unfilled_buf`, with enables using the unfilled part of a cursor as a `BorrowedBuf`. Note that unlike the ACP, `BorrowedCursor::unfilled_buf` was moved to a `From` conversion. This is more consistent with other ways of creating a `BorrowedBuf` and hides a bit this conversion that requires unsafe code to be used correctly.
If the remote process is terminated by a signal, make `remote-test-client` exit with the code `128 + <signal-number>` instead of always `3`. This follows common practice among tools such as bash [^1]: > When a command terminates on a fatal signal whose number is N, Bash uses the > value 128+N as the exit status. It also allows us to differentiate between `run-pass` and `run-crash` ui tests without special case code in compiletest for that when `remote-test-client` is used.

This allows efficient implementations for random sources that generate a word at a time.
This will let people make calls like random(1..=6), and allows for future expansion to non-uniform distributions, as well as floating-point. For now, this is only implemented for `RangeFull`, to get the interface in place. Subsequent commits will implement it for other range types.

wrapping shift: remove first bitmask and table
```rust
#[inline(always)]
pub const fn wrapping_shl(self, rhs: u32) -> Self {
// SAFETY: the masking by the bitsize of the type ensures that we do not shift
// out of bounds
unsafe {
self.unchecked_shl(rhs & (Self::BITS - 1))
}
}
```
already does the bitmask, so it seems unnecessary here.

…, r=Mark-Simulacrum remote-test-client: Exit code `128 + <signal-number>` instead of `3` If the remote process is terminated by a signal, make `remote-test-client` exit with the code `128 + <signal-number>` instead of always `3`. This follows common practice among tools such as bash [^1]: > When a command terminates on a fatal signal whose number is N, Bash uses the > value 128+N as the exit status. It also allows us to differentiate between `run-pass` and `run-crash` ui tests without special case code in compiletest for that when `remote-test-client` is used. See rust-lang#143002 and in particular rust-lang#143002 (comment). Exiting with code `3` has been done from the start (see rust-lang#39400) and seems arbitrary rather than a deliberate design decision, so changing it does not seem like an extraordinarily big deal. ### Regression testing Note that rust-lang#143002 will act as a regression test once it is rebased on this PR. ### Why a separate PR I think it is comforting to know that CI does not break with just this change. But if my reviewer prefers, we can move this commit to be part of rust-lang#143002 instead. [^1]: https://www.gnu.org/software/bash/manual/html_node/Exit-Status.html
…acrum UWP: link ntdll functions using raw-dylib Lazy loading isn't necessary so there's no need for the added complexity and overhead. However, it may be that people using UWP rust libraries don't have the necessary import libraries linked by Visual Studio so this uses raw-dylib, which allows linking to DLL functions without having an import library. This is a somewhat temporary situation as raw-dylib is intended to eventually be the default for all imports. When that happens, this special case can be removed. Closes rust-lang#143530
