Joe Loser 1b3a78d1d5 [clang] Use std::size instead of llvm::array_lengthof ...

LLVM contains a helpful function for getting the size of a C-style
array: `llvm::array_lengthof`. This is useful prior to C++17, but not as
helpful for C++17 or later: `std::size` already has support for C-style
arrays.

Change call sites to use `std::size` instead. Leave the few call sites that
use a locally defined `array_lengthof` that are meant to test previous bugs
with NTTPs in clang analyzer and SemaTemplate.
