libstdc++: Fix subrange::advance and subrange::prev (LWG 3433)
This implements the proposed resolution of LWG 3433, which fixes
subrange::advance when called with a negative argument.
libstdc++-v3/ChangeLog:
LWG 3433 subrange::advance(n) has UB when n < 0
* include/std/ranges (subrange::prev): Fix typo.
(subrange::advance): Handle a negative argument as per the proposed
resolution of LWG 3433.
* testsuite/std/ranges/subrange/lwg3433.cc: New test.
