Original commit message: [mac][wasm] Work around MacOS 11.2 code page decommit failures MacOS 11.2 refuses to set "no access" permissions on memory that we previously used for JIT-compiled code. It is still unclear whether this is WAI on the part of the kernel. In the meantime, as a workaround, we use madvise(..., MADV_FREE_REUSABLE) instead of mprotect(..., NONE) when discarding code pages. This is inspired by what Chromium's gin platform does.
