Look at the debugging library which objdump and objcopy use. The
interface is binutils/debug.h. Look at read_debugging_info in
binutils/rddbg.c to get debugging information for a file. Then call,
e.g., debug_find_tagged_type to get the struct you want, call
debug_get_fields to get the fields, and call debug_get_field_bitpos on
each field to get the bit position within the struct.
