dwarf2out.c (expand_builtin_init_dwarf_reg_sizes): If DWARF_FRAME_RETURN_COLUMN doesn't have a register mode, use Pmode.

* dwarf2out.c (expand_builtin_init_dwarf_reg_sizes):
If DWARF_FRAME_RETURN_COLUMN doesn't have a register mode, use Pmode.

* unwind-dw2.c (_Unwind_GetGR): Use dwarf_reg_size_table
to decide if to access a _Unwind_Ptr or a _Unwind_Word.
(_Unwind_SetGR): Likewise.
(_Unwind_GetPtr, _Unwind_SetSpColumn): New functions.
(Unwind_SpTmp): New typedef.
(uw_update_context_1): Use _Unwind_SetSpColumn and _Unwind_GetPtr.
(uw_update_context): Use _Unwind_GetPtr.
(init_dwarf_reg_size_table): Move above uw_init_context_1.
(uw_init_context_1): Initialize dwarf_reg_size_table if necessary.
Use _Unwind_SetSpColumn.
(uw_install_context_1): Don't initialize dwarf_reg_size_table.
Use _Unwind_GetPtr.
