realigned and dynamic realigned argument pointer isn't used.

when stack is realigned.

* dwarf2out.c (dw_fde_struct): Add stack_realignment, drap_reg,
vdrap_reg, stack_realign and drap_reg_saved.
(add_cfi): Don't allow redefining CFA when DRAP is used.
(reg_save): Handle stack alignment.
(dwarf2out_frame_debug_expr): Add rules 16-20 to handle stack
alignment. Don't generate DWARF information for (set fp sp)
when DRAP is used.
(dwarf2out_begin_prologue): Initialize drap_reg and vdrap_reg
to INVALID_REGNUM.
(int_loc_descriptor): Move prototype forward. Also define if
DWARF2_UNWIND_INFO is true.
(output_cfa_loc): Handle DW_CFA_expression.
(build_cfa_aligned_loc): New.
(based_loc_descr): Update assert for stack realign. For local
variables, use sp+offset when stack is aligned without drap and
fp+offset when stack is aligned with drap. For arguments, use
cfa+offset when drap is used to align stack.
