Convert arm targets to new FRAME interface.
* arm-tdep.c (struct frame_extra_info): Remove fsr.
(arm_frame_find_save_regs): Delete.
(arm_frame_init_saved_regs): New.
(arm_init_extra_frame_info): Alloacte saved_regs as required.
Allocate extra_info as required.  Convert all uses of fsr.regs
to use saved_regs, similarly all uses of EXTRA_FRAME_INFO fields
to use extra_info.
(thumb_scan_prologue, arm_scan_prologue, arm_find_callers_reg)
(arm_frame_chain, arm_frame_saved_pc, arm_pop_frame): Likewise.
(check_prologue_cache, save_prologue_cache): Likewise.
(_initialize_arm_tdep): Ensure prologue_cache is correctly set up.
* config/arm/tm-arm.h (EXTRA_FRAME_INFO): Delete.
(FRAME_FIND_SAVED_REGS): Delete.
(arm_frame_find_saved_regs): Delete prototype.
(arm_frame_init_saved_regs): New prototype.
(FRAME_INIT_SAVED_REGS): Define.
