[PATCH 2/2] use zuinteger_unlimited for heuristic-fence-post

[Yao Qi <yao@codesourcery.com>]

Hi,
The comment here gives me a feeling that we should convert this
command to zuinteger_unlimited_cmd.

gdb:

2013-02-15  Yao Qi  <yao@codesourcery.com>

	* alpha-tdep.c (_initialize_alpha_tdep): Call
	add_setshow_zuinteger_unlimited_cmd instead of
	add_setshow_zinteger_cmd.
	Remove comments.
	* mips-tdep.c (_initialize_mips_tdep): Likewise.
