[Clang] Remove __is_nullptr (#99038)
`is_null_pointer` can be implemented very efficiently as
`__is_same(__remove_cv(T), decltype(nullptr))`. Since GCC supports both
of these builtins as well, libc++ has no interest in using
`__is_nullptr` instead. Furthermore, I could find only a single use in
the wild
(https://sourcegraph.com/search?q=context:global+__is_nullptr%28+-file:clang&patternType=keyword&sm=0).
Because of these reasons I don't think it's worth keeping this builtin
around.
