WASM interpreter requires that parameters are stored in big-endian natural
memory order (higher bits on lower addresses and lower bits on higher address).
On the other hand, WASM compiled code naturally stores data in memory in
little-endian order. This CL implements big-endian support for passing
double and int64 parameters to WASM interpreter.
