The semantics of DW_CFA_GNU_args_size have changed subtile over the
...
years. Adopt the new convention that it is call-site specific and that
it should be applied before moving the IP by personality routines, but
not during normal unwinding. Further discussion can be found in
LLVM's phabricator review D38680.

Fix DW_CFA_GNU_args_size handling. The primary architecture using this
...
opcode is VAX. A function call pushes the number of arguments given onto
the stack and "ret" will pop it automatically. The FDE of the caller
contains the amount of stack space used for arguments (and possibly
extra padding), so unwinding has to compensate for this when "returning"
from a function. This is exactly the case when step() is done. The
existing handling in _Unwind_SetIP no longer makes sense.
