This patch fixes the static link description in DWARF to comply with the
specification. In order to do so, it appends a field to all FRAME
objects to hold the frame base address (DW_AT_frame_base) so that the
nested subrograms can directly reference this field.

See <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53927> for the context
(in particular why we need this additional field in FRAME objects).

Ping for the patch submitted in<https://gcc.gnu.org/ml/gcc-patches/2015-07/msg01629.html>.
