[Committed] Handle COPYSIGN in dwarf2out.cc's mem_loc_descriptor.

Many thanks to Hans-Peter Nilsson for reminding me that new RTX codes
need to be added to dwarf2out.cc's mem_loc_descriptor, and for doing
this for BITREVERSE.  This patch does the same for the recently added
COPYSIGN.  I'd been testing these on a target that doesn't use DWARF
(nvptx-none) and so didn't exhibit the issue, and my additional testing
on x86_64-pc-linux-gnu to double check that changes were safe, doesn't
(yet) trigger the problematic assert in dwarf2out.cc's mem_loc_descriptor.
