Fix conversions from pointer to tcg_target_long

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long (suggested by Blue Swirl).

These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.
