that was present in a prior declaration, emit a warning rather than a
hard error (which we did before, and still do with mismatched
exception specifications). Moreover, provide a fix-it hint with the
throw() clause that should be added, e.g.,
t.C:10:7: warning: 'operator new' is missing exception specification
'throw(std::bad_alloc)'
void *operator new(unsigned long sz)
^
throw(std::bad_alloc)
As part of this, disable the warning when we're missing an exception
specification on operator new, operator new[], operator delete, or
operator delete[] when exceptions are turned off (-fno-exceptions).
Fixes PR5957.
