* dwarf2-frame.c (struct dwarf2_cie): Add ptr_size member.
Throughout, call read_encoded_value with ptr_size rather than addr_size.
(decode_frame_entry_1): Remove redundant setting of
addr_size. Call gdbarch_dwarf2_addr_size rather than gdbarch_ptr_bit
to determine addr_size in Dwarf versions < 4. Set ptr_size dependent
on examined frame section. Add comment to explain why.
* gdbarch.sh (dwarf2_addr_size): Define as variable. Add lengthy
comment to explain usage.
* gdbarch.c: Regenerate.
* gdbarch.h: Regenerate.
* xstormy16-tdep.c (xstormy16_gdbarch_init): Set dwarf2_addr_size to 4.
