Pointers are the idiomatic way to express "optional, by-reference" in LLVM.
By contrast, optional<Token&> is illegal, and optional<token*> is unidiomatic

It is mentioned - Loc must be a spelling location.

done (I think). FileID rather than file here, because it's not true (or at
least not clear) about files.

+ bool AcceptLeft = Right != All.begin() && !((Right - 1)->endLocation() <
Loc);
+ return llvm::makeArrayRef(Right - int(AcceptLeft), Right + int(AcceptRight));

Replaced with an explicit ternary instead, which is (maybe) clearer?
