This makes the bulk memory operations respect the memory type, i.e.
using i64 values for memory offsets if memory64 is enabled.
The called C functions now expect memory offsets to be passed as
{uintptr_t}, such that we can address any memory on all systems. For
64-bit memories on 32-bit systems, the upper half of the 64-bit value is
checked in compiled code before passing the lower half to the C
function.
Liftoff support turned out to be a bit harder than expected, because we
cannot hold three 64-bit values in registers on ia32 (not enough
registers...). Thus implement that in a follow-up CL.
