The same happens for g++.dg/template/pretty1.C and
g++.old-deja/g++.ext/pretty2.C - both fail with -flto/-fwhopr in r165220, but
not in r165152. It seems __FUNCTION__ and __PRETTY_FUNCTION__ is broken too in
constructors and destructors.

g++.old-deja/g++.ext/pretty2.C actually gives nice output:

$ g++ g++.old-deja/g++.ext/pretty2.C && ./a.out
ctor
__FUNCTION__ X
__PRETTY_FUNCTION__ X::X()
member fn
__FUNCTION__ fn
__PRETTY_FUNCTION__ void X::fn()
conversion
__FUNCTION__ operator int
__PRETTY_FUNCTION__ X::operator int()
dtor
__FUNCTION__ ~X
__PRETTY_FUNCTION__ X::~X()

$ g++ g++.old-deja/g++.ext/pretty2.C -flto && ./a.out
ctor
__FUNCTION__ 
__PRETTY_FUNCTION__ 
member fn
__FUNCTION__ fn
__PRETTY_FUNCTION__ void X::fn()
conversion
__FUNCTION__ operator int
__PRETTY_FUNCTION__ X::operator int()
dtor
__FUNCTION__ 
__PRETTY_FUNCTION__
