arm: Use REG_CFA_REGISTER instead of UNSPEC_STACK_ALIGN.
This requires a bit of extra preparation in arm_unwind_emit, in
order to handle the change for ARM unwinding.
* config/arm/arm.c (arm_dwarf_handle_frame_unspec): Remove.
(TARGET_DWARF_HANDLE_FRAME_UNSPEC): Remove.
(arm_expand_prologue): Use REG_CFA_REGISTER to mark the
stack pointer save.
(arm_unwind_emit_set): Don't recognize UNSPEC_STACK_ALIGN.
(arm_unwind_emit): Walk REG_NOTES for unwinding notes. Emit
proper unwind info for a REG_CFA_REGISTER save of stack pointer.
* config/arm/arm.md (UNSPEC_STACK_ALIGN): Remove.
