PR10923 Handle AT_frame_base given by DW_OP_call_frame_cfa in .debug_frame.
dwarf_cfi_addrframe should not be called with pc adjusted to the bias
of the dwfl_module_dwarf_cfi or dwfl_module_eh_cfi. This just happened to
work in the .eh_frame case because bias was always zero.
* dwflpp.cxx (get_cfa_ops): Don't adjust pc for bias.
