25c1d7a3 - [clang] Don't warn on zero literals with -std=c2y (#149688)

[clang] Don't warn on zero literals with -std=c2y (#149688) Fixes #149669; the old check compared with the end of the literal, but we can just check that after parsing digits, we're pointing to one character past the token start. (cherry picked from commit 8366dc207a2e6b50cb8afe2d98fca68bd78bd0fa)
