libstdc++: Improve std::forward static assert message
The previous message told you something was wrong, but not why it
happened or why it's bad. This changes it to explain that the function
is being misused.
Signed-off-by: Jonathan Wakely <jwakely@redhat.com>
libstdc++-v3/ChangeLog:
* include/bits/move.h (forward(remove_reference_t<T>&&)):
Improve text of static_assert.
* testsuite/20_util/forward/c_neg.cc: Adjust dg-error.
* testsuite/20_util/forward/f_neg.cc: Likewise.
