Setting WASM_BIGINT enables support for using the bigint type in JS to pass 64-bit integers. This allows compiling lua with full 64-bit integer/float support. I ran this against my (fairly large) lua application and it seemed to resolve all the issues I was previously having with large numbers in lua.

This is fantastic. I'm very happily surprised that compiler option exists

This conversion seems odd. Should luaL_ref now return bigint?

It does seem a bit strange, but this matches the lua function definitions:

LUA_API int (lua_rawgeti) (lua_State *L, int idx, lua_Integer n);
// ...
LUALIB_API int (luaL_ref) (lua_State *L, int t);
