Hi,

this patch replaces the only occurence of LOWEST_PC macro in arm target by itsexpression and replaces
current_gdbarch with get_frame_arch.

Tested by builing arm target. Ok to commit?

ChangeLog:

	* arm-tdep.c (arm_prologue_this_id): Replace LOWEST_PC by its
	expression and use get_frame_arch to replace current_gdbarch by frame's
	architecture.
	* arm-tdep.h (LOWEST_PC): Remove.
