wasm64: emscripten library functions which take pointers throw TypeError: Cannot convert number to BigInt

[jspanchu]

Methods like emscripten_set_main_loop_arg and html5 callback functions which take a void* userData as their second parameter throw TypeError: Cannot convert number to BigInt.

This can easily be reproduced by compiling test/emscripten_api_browser.c with memory64 flag.

emcc test/emscripten_api_browser.c -o index.html -sMEMORY64=1

Output:
