[PATCH] D127363: [Lex] Fix for char32_t literal truncation on 16 bit architectures

This sounds correct to me, though I don't feel like an expert here.
Upstream in non-experimental IntWidth == Char32Width except on AVR, so it won't actually break anything.

Regarding testing, it seems like this should change the diagnostic emitted for `long x = 'abc'` from "Character constant too long for its type" to "Multi-character character constant" when the target is AVR?
