additional edge cases tests for `path.rs` 🧪
This pull request adds a few new edge case tests to the `std::path` module. The new tests cover scenarios such as paths with only separators, non-ASCII and Unicode characters, embedded new lines, etc. Each new test is documented with some helpful in-line comments as well.

The previous commit moved all test files from `std` to `core` so git
understands the move. Not all functionality is actually testable in
`core`, however, so perform move the relevant portions back. Changes
from inherent to module methods is also done since this is the form of
math operations available in `core` (as `core_float_math`).
|
|
Many float-related tests in `std` only depend on `core`, so move the
tests there. This also allows us to verify functions from
`core_float_math`.
Since the majority of test files need to be moved to `coretests`, move
the files here without any cleanup; this is done in a followup commit.
This makes git history slightly cleaner, but coretests will not build
immediately after this commit.

1. analogous to std::cell::Ref(Mut)::filter_map.
2. doesn't imply `Try` genericizability.
|
|
New compiler configuration has been introduced that is designed to
replace the build script configuration `reliable_f16`, `reliable_f128`,
`reliable_f16_math`, and `reliable_f128_math`. Do this replacement here,
which allows us to clean up `std`'s build script.
All tests are gated by `#[cfg(bootstrap)]` rather than doing a more
complicated `cfg(bootstrap)` / `cfg(not(bootstrap))` split since the
next beta split is within two weeks.

fix pthread-based tls on apple targets
Tries to fix #127773.
|
|
|
|
Mark some std tests as requiring `panic = "unwind"`
This allows these test modules to pass on builds/targets without unwinding support, where `panic = "abort"` - the ignored tests are for functionality that's not supported on those targets.

Add `From<{integer}>` for `f16`/`f128` impls
This PR adds `impl From<{bool,i8,u8}> for f16` and `impl From<{bool,i8,u8,i16,u16,i32,u32}> for f128`.
The `From<{i64,u64}> for f128` impls are left commented out as adding them would allow using `f128` on stable before it is stabilised like in the following example:
```rust
fn f<T: From<u64>>(x: T) -> T { x }
fn main() {
let x = f(1.0); // the type of the literal is inferred to be `f128`
}
```
None of the impls added in this PR have this issue as they are all, at minimum, also implemented by `f64`.
This PR will need a crater run for the `From<{i32,u32}>` impls, as `f64` is no longer the only float type to implement them (similar to the cause of #125198).

The LLVM issue [1] was fixed with [2], which is included in the LLVM20
upgrade. Tests no longer fail, so enable them here.

Windows: remove readonly files
When calling `remove_file`, we shouldn't fail to delete readonly files. As the test makes clear, this make the Windows behaviour consistent with other platforms. This also makes us internally consistent with `remove_dir_all`.

std: move `io` module out of `pal`, get rid of `sys_common::io`
Part of #117276.
This does two related things:
1. It moves the platform-specific definitions for `IoSlice`, `IoSliceMut` and `is_terminal` out of `pal` and into `sys` and unifies some of them.
2. It gets rid of `sys_common::io`, moving the non-platform-specific test helpers into `std::test_helpers` and the buffer size definition to the new `sys::io` module.

While working on #122661, some of these started triggering our "unnecessary parens" lints due to a change in the `assert!` desugaring. A cursory search identified a few more. Some of these have been carried from before 1.0, were a bulk rename from the previous name of `assert!` left them in that state. I went and removed as many of these unnecessary parens as possible in order to have fewer annoyances in the future if we make the lint smarter.

This removes two minor OnceLock tests which test private methods. The
rest of the tests should be more than enough to catch mistakes in those
private methods. Also makes ReentrantLock::try_lock public. And finally
it makes the mpmc tests actually run.

This does need EMCC_CFLAGS="-s MAXIMUM_MEMORY=2GB" avoid several OOMs.
