…32-msvc targets also mention the MSVC alignment issue in platform-support.md
- With `Context` wrapped by `SmirInterface`, the stable-mir's TLV stores a pointer to `SmirInterface`, while the rustc-specific TLV stores a pointer to tables. - This PR make the `rustc_smir` mod public.

This commit adjusts feature implication of the RISC-V ISA for better
feature detection from the user perspective.
The main rule is:
If the feature A is a functional superset of the feature B (A ⊃ B),
A is to imply B, even if this implication is not on the manual.
Such implications (not directly referred in the ISA manual) are commented
as "A ⊃ B" which means "A is a (functional) superset of B".
1. Zbc → Zbkc (add as a superset)
The Zbkc extension is a subset of the Zbc extension
(Zbc - "clmulr" instruction == Zbkc)
2. Zkr → (nothing) (remove dependency to Zicsr)
Implication to the Zicsr extension is removed because (although nearly
harmless), the Zkr extension (or the "seed" CSR section) defines its own
subset of the Zicsr extension.
3. Zvbb → Zvkb (comment as a superset)
This implication was already there but not denoted as a functional
superset. This commit adds the comment.
4. Zvfh → Zvfhmin (comment as a superset)
This is similar to the case above (Zvbb → Zvkb).
5. Zvfh → Zve32f (add implication per the ISA specification)
This dependency is on the ISA manual but was missing (due to the fact
that Zvfh indirectly implies Zve32f on the current implementation
through Zvfh → Zvfhmin, which is a functional relation).
This commit ensures that this is *also* ISA-compliant in the
source code level (there's no functional changes though).
6. Zvknhb → Zvknha (add as a superset)
The Zvknhb extension (SHA-256 / SHA-512) is a functional superset of
the Zvknha extension (SHA-256 only).
Although `Env` (as `Vars`), `Args`, path functions, and OS constants are publicly exposed via `std::env`, their implementations are each self-contained. Keep them separate in `std::sys` and make a new module, `sys::env`, for `Env`.
These have grown out of sync with the platforms.
Also, update the same pattern of reuse in `sys::args` to match.
Specifically, this allows string literal patterns to be used where a `str` is expected when `deref_patterns` is enabled.
Specifically, this allows byte string literal patterns to be used where a `[u8]` or `[u8;N]` is expected when `deref_patterns` is enabled.
This has other warnings if necessary and doesn't need extra warnings from this FCW. cc rust-lang#138762
Certain filesystems for large monorepos are slow to service individual read requests, but can service many in parallel. This change brings down the time to run a single cached test on one of those filesystems from 40s to about 8s.
The `synstructure` docs say "This method is a no-op, underscore consts are used by default now." The behaviour change occurred going from `synstructure` version 0.13.0 to 0.13.1.
…ib run-make test Dynamic libraries on AIX have the ".a" extension. The c-link-to-rust-dylib run-make test checks for the extension explicitly, so the extension for AIX is also added to accommodate the test case on AIX.
