[PATCH 04/26] alpha-tdep.c/mips-tdep.c: "set heuristic-fence-post" is signed/zinteger.

These commands are currently var_zinteger, hence their control
variable is signed.

* alpha-tdep.c (heuristic_fence_post): Change type to int.
(alpha_heuristic_proc_start): Adjust to check -1 instead of
UINT_MAX.
* mips-tdep.c (heuristic_fence_post): Change type to int.
(heuristic_proc_start): Adjust to check -1 instead of UINT_MAX.
