The bug only happen in member functions,
I tried multiple classes with deducted return type for multiple member
functions, they all point to the same DW_TAG_unspecified_type.

g++ 4.8.2 on intel-Linux regress again. DW_TAG_rvalue_reference_type did not
get generated.
g++ 4.8.2 on intel Solaris is broken too.
g++ 4.9.0 works on intel-Linux but not on intel

Note, this is a const static member, the initialization is the definition,
if I don't initialize it, I would get an Undefined symbol linking error
