Fix PR12616 - gdb does not implement DW_AT_data_bit_offset
The DW_AT_data_bit_offset attribute was introduced by DWARF V4 and
allows specifying the offset of a data member within its containing
entity. But although the new attribute was intended to replace
DW_AT_bit_offset for this purpose, GDB ignores it, and thus GCC still
emits DW_AT_bit_offset instead. See also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71669.
This change fixes GDB's lack of support for DW_AT_data_bit_offset and
adds an appropriate test case.
gdb/ChangeLog:
PR gdb/12616
* dwarf2read.c (dwarf2_add_field): Handle the DWARF V4 attribute
DW_AT_data_bit_offset.
gdb/testsuite/ChangeLog:
PR gdb/12616
* gdb.dwarf2/nonvar-access.exp: New testcase. Check that GDB
respects the DW_AT_data_bit_offset attribute.
