[IMCC] Fix builds on amd64. r32694 changed some variables to size_t, but now a pointer to a size_t was passed to get_codesize() as an int*.  On linux/amd64, int is 32 bit and size_t is 64 bit, thus, the high 32 bits were uninitialized and miniparrot crashed immediately when trying to allocate a 140TB buffer.
