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.

There are many "(long)tb" in exec.c and the types of tb_next in
TranslationBlock, tc_ptr in tb_find_pc(), searched_pc etc. are
"unsigned long". So more patches for w64 are needed.

Yes, I am very aware of this fact. This is the third effort to
get QEMU code which is w64 clean. The first two were large
patches which were difficult to review. Now I send small
patches which will finally achieve the same goal. Sometimes
these small patches seem to be unrelated to w64 (like
a recent patch which removes a parameter). I think that
increasing portability of software has positive effects for
all targets, not only the new one. That's why I do this
although I don't use w64.
