This Godbolt shows that clang considers `struct S { volatile int i; };` "trivially relocatable", but `volatile int` is considered "not-trivially relocatable". This is inconsistent. It's also inconsistent with the behavior of `std::is_trivially_copyable_v<volatile int> == true`. `__is_trivially_relocatable` should do the same. Otherwise, we end up with a type that is trivially copyable but not trivially relocatable.

Consistent with `__is_trivially_copyable(volatile int) == true` and `__is_trivially_relocatable(volatile Trivial) == true`, `__is_trivially_relocatable(volatile int)` should also be `true`. Fixes llvm#77091 [clang] [test] New tests for __is_trivially_relocatable(cv-qualified type)
