RefCell::replace_with is not stablized in this PR, since it wasn't part of the RFC.

I'm not allowed to have the same feature flag associated with multiple stability levels.

Fixes rust-lang#46263.

The `--sort-modules-by-appearance` option will list modules in the
order that they appear in the source, rather than sorting them
alphabetically (as is the default). This resolves rust-lang#8552.

- make liblibc to point to libc with aarch64-unknown-openbsd
- make c_char (in std::os::raw) to point to right value

Closes rust-lang#46670.

… position

Outputs in InlineAsm can be read-write, so splitting it out is useful for things like Store-Store folding, as it cannot be done for a Store-AsmOutput.

This PR is intended to make no changes, just be the mechanical split of the enum.  Future changes can use the split, like a MIR pass I'm working on and perhaps two-phase borrows.

add aarch64-unknown-openbsd support

- make liblibc to point to libc with aarch64-unknown-openbsd
- make c_char (in std::os::raw) to point to right value

r? @alexcrichton

currently, I have only tested in crosscompilation environement (openbsd x64_64 -> openbsd aarch64). it produces valid binaries.

Add an option to allow rustdoc to list modules by appearance

Distribute intrinsic.natvis with the compiler for windows-msvc.

This adds `intrinsic.natvis` to the `windows-msvc` distributions of Rust, enabling the visualization of `str` and slices in the VS debugger. Two other natvis files are already included, this was probably just an oversight.

I also updated `rust-windbg.cmd` to load this file as well.

Add Hash impl for SystemTime and Instant

Closes rust-lang#46670.

Not sure how to actually test non-Linux platforms.
`rustc --target=i686-pc-windows-gnu --crate-name std --crate-type rlib src/libstd/lib.rs -o q.rlib` works a bit, but for Redox I'm not sure what to do.

Split PlaceContext::Store into Store & AsmOutput
