When we're compiling compiler_rt for any WebAssembly target, we do not want to expose all the compiler-rt functions to the host runtime. By setting the visibility of all exports to `hidden`, we allow the linker to resolve the symbols during linktime, while not expose the functions to the host runtime. This also means the linker can properly garbage collect any compiler-rt function that does not get resolved. The symbol visibility for all target remains the same as before: `default`.
