[Bug preprocessor/39818] New: cpp_macro_definition should preserve # and ## spelling and whitespace

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

cpp_macro_definition, as used by options such as -dM, for PCH and
for outputting macro definitions in debug info, should preserve the
spelling (digraph or not) of # and ## operators, whether there is
whitespace around them and sequences of consecutive ## and %:%:
operators.  After my patch for bug 20078, the relevant information
is available at this point; it just isn't used for the textual output.
