print compressed pdata structure as described on MSDN. This only
applies to a limited set of architectures (ARM, SH4).
(slurp_symtab, my_symbol_for_address): Define static helper
functions for pe_print_compressed_pdata.
* coffcode.h (bfd_coff_backend_data): Add _bfd_coff_print_pdata field.
(bfd_coff_have_print_pdata, bfd_coff_print_pdata): Define.
* bfd/peXXigen.c (_bfd_XX_print_private_bfd_data_common): Add check on
bfd_coff_backend_data, call the function if non-null.
