This is an alternative approach to https://github.com/llvm/llvm-project/pull/169769. We increase the size of the old `Integral<Bits, Signed>` to 24 bytes (on a 64 bit system) and introduce a new `Char<Signed>` that's used for the old `PT_Sint8` and `PT_Uint8` primitive types. The old approach did not work out in the end because we need to be able to do arithmetic (but essentially just `+` and `-`) on the offsets of such integers-that-are-actually-pointers. c-t-t-: https://llvm-compile-time-tracker.com/compare.php?from=723d5cb11b2a64e4f11032f24967702e52f822bc&to=16dc90efebbf52e381c7655131b2fb74c307cc42&stat=instructions:u
