Subject: [v3] fix std::result_of support for cv-quals

This fixes a couple of bugs I noticed in std::result_of, the first new
test covers those bugs, the second new test is just taken from the
standard to test result_of a little more thoroughly.

        * include/std/type_traits (result_of): Fix handling of cv-quals.
        * testsuite/20_util/result_of/1.cc: New.
        * testsuite/20_util/result_of/2.cc: New.
        * testsuite/20_util/declval/requirements/1_neg.cc: Adjust dg-error
        line numbers.
        * testsuite/20_util/make_signed/requirements/typedefs_neg.cc:
        Likewise.
        * testsuite/20_util/make_unsigned/requirements/typedefs_neg.cc:
        Likewise.

Tested x86_64-linux, committed to trunk.
