One could not run it like the following, for the would be a panic:
cargo run --manifest-path ci/date-check/Cargo.toml .
Also, remove the need to specify argument, in which case, current_dir
is assumed.

Add the armv4t-none-eabi target to the supported_targets
This target was added in #100244 but forgot to add it to the macro in the `mod.rs` file.

Add support for generating unique profraw files by default when using `-C instrument-coverage`
Currently, enabling the rustc flag `-C instrument-coverage` instruments the given crate and by default uses the naming scheme `default.profraw` for any instrumented profile files generated during the execution of a binary linked against this crate. This leads to multiple binaries being executed overwriting one another and causing only the last executable run to contain actual coverage results.
This can be overridden by manually setting the environment variable `LLVM_PROFILE_FILE` to use a unique naming scheme.
This PR adds a change to add support for a reasonable default for rustc to use when enabling coverage instrumentation similar to how the Rust compiler treats generating these same `profraw` files when PGO is enabled.
The new naming scheme is set to `default_%m_%p.profraw` to ensure the uniqueness of each file being generated using [LLVMs special pattern strings](https://clang.llvm.org/docs/SourceBasedCodeCoverage.html#running-the-instrumented-program).
Today the compiler sets the default for PGO `profraw` files to `default_%m.profraw` to ensure a unique file for each run. The same can be done for the instrumented profile files generated via the `-C instrument-coverage` flag as well which LLVM has API support for.

Use llvm-libunwind="in-tree" for Fuchsia targets
With updates to Fuchsia CI's Zircon libraries #99833, we can introduce `llvm-libunwind="in-tree"` for Fuchsia targets. This PR restores functionality removed from https://github.com/rust-lang/rust/pull/93604#issuecomment-1136515651.

linker-plugin-lto.md: Correct the name of example c file
The final output is linked with `cmain.o`, but we use `main.o` in the example.
This patch changes the name to `cmain.c` and `cmain.o` as the "C/C++ code as a dependency in Rust" section.

This diagram is based on the diagram in Joshua Nelson's talk on
bootstrapping at RustConf 2022 [1]. I converted it to Mermaid and made
some tweaks to simplify it and bring it closer to bootstrap's
terminology, and then Ralf Jung added nodes for copying artifacts.

This is implementing the MCP from rust-lang/compiler-team#493. It is
increasing the minimum requirements of a couple Tier 1 targets, and
others at lower tiers, so this should go through FCP sign-offs for both
`T-compiler` and `T-release`.
The new `linux-gnu` baseline is kernel 3.2 and glibc 2.17. We will also
take that kernel as the minimum floor for _all_ `*-linux-*` targets, so
it may be broadly assumed in the implementation of the standard library.
That does not preclude specific targets from having greater requirements
where it makes sense, like a new arch needing something newer, or a
platform like `linux-android` choosing a newer baseline.

This led to a more robust regex, though making the tool more picky.
It also found a wrong date format that was missed.
