I synced #81267 and unfortunately there is one issue
```
libc/src/__support/integer_literals.h:122:28: error: class template partial specialization contains a template parameter that cannot be deduced; this partial specialization will never be used [-Wunusable-partial-specialization]
template <size_t N> struct Parser<LIBC_NAMESPACE::cpp::UInt<N>> {
                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
libc/src/__support/integer_literals.h:122:18: note: non-deducible template parameter 'N'
template <size_t N> struct Parser<LIBC_NAMESPACE::cpp::UInt<N>> {
```
I need to think this through.
