- add tests for `a == b` where missing - try to make all the tests more similar - try to use more illustrative test values
`<` seems to be the "lucky one" for llvm
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.

For the zkVM, even when a guest buffer is uninitialized, from the host's perspective it is just a normal piece of memory which was initialized before letting the guest write into it. This makes `sys_read` safe to use with an uninitialized buffer. See risc0/risc0#2853.
Includes `f16` symbols on MIPS [1], updates for `libm` [2], and reapplies the patch that drops the `public_test_deps!` macro [3]. [1]: rust-lang/compiler-builtins#762 [2]: rust-lang/compiler-builtins#765 [3]: rust-lang/compiler-builtins#766
It seems as if `f16` works on MIPS now according to my testing on Rust master with LLVM 20, and I was asked to create PRs with my changes. I only tested on the flavour of `mipsel-unknown-linux-gnu` hardware that happens to be available to me, so I can't say anything about other MIPS hardware, but from a casual skimming of the LLVM code ([1], [2]) it seems like `f16` should work on all MIPS hardware. So enable it for all MIPS hardware.

There is a time window during which the OS can terminate a thread before stdlib can retreive its `Packet`. Currently the `Thread::join` panics with no message in such an event, which makes debugging difficult; fixes rust-lang#124466.
