* mep-tdep.c (struct mep_prologue): Add gdbarch member.

Browse Source 
(check_for_saved): Use it instead of current_gdbarch.
	(is_arg_spill): Add gdbarch paramter.  Use it instead
	of current_gdbarch.
	(mep_analyze_prologue): Add gdbarch parameter.  Pass it
	to is_arg_spill and check_for_saved.
	(mep_skip_prologue, mep_analyze_frame_prologue): Update calls.
