c: Do not register nullptr_t built-in type [PR114869]
As reported in bug 114869, the C front end wrongly creates nullptr_t
as a built-in typedef; it should only be defined in <stddef.h>. While
the type node needs a name for debug info generation, it doesn't need
to be a valid identifier; use typeof (nullptr) instead, similar to how
the C++ front end uses decltype(nullptr) for this purpose.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.
