wasm: align fiber stack pointer to 16 bytes

In WebAssembly C ABI, the linear stack pointer must be always aligned
to 16 bytes like other archs.
The misaligned stack pointer causes some weird memory corruption since
compiler assumes the aligned stack pointer.

coroutine/arm64: Skip saving/restoring x30 twice and use `autiasp`

2023-12-22T02:30:00+00:00

We don't need to save/restore x30 twice, and we can just use `ret`,
which uses x30 as return address register instead of explicit `ret `
instruction. This also allows us to use `autiasp` instead of `autia1716`
and we can skip setting SP/LR to x16/x17.

Also the size of register save area is shrunk by 16 bytes due to the
removal of extra x30 save/restore.

Do not use non-ASCII chars in sources

2023-11-04T17:14:26+00:00

No encodings are guaranteed in C compilers, and other than UTF-8
encodings may be assumed in some platforms, e.g., CP932 on Windows
Japanese edition, and may result in compilation errors.

Avoid memory dependency between instructions. (#8284)
