fitzgen opened PR #10461 from fitzgen:remove-unnecessary-unsafe-cells-in-gc-runtime-code to bytecodealliance:main:

None of these are actually mutated while behind shared references. Everything, including interactions with JIT code, obeys Rust's borrowing rules. Running tests under MIRI still passes, verifying these claims. Therefore, we can remove these UnsafeCells, which makes the code much easier to read and much less footgun-y since there is less unsafe code and less working with UnsafeCells' raw pointers.

Drive-by review for unrelated code, SendSyncPtr can remove the need for these

More drive-by review: perhaps adding an unsafe fn as_slice(&self) to Mmap? (same for above for the drc heap)
