[PATCH] D70452: [scudo][standalone] Minor optimization & improvements

[Kostya Kortchinsky via Phabricator via llvm-commits]

cryptoad added a comment.

And I forgot in the message the part about only checking `Size` and not `NeededSize`, adding  compiler check to make sure we do not overflow a `uptr`.
This allows us to skip a check, and doesn't impact our security.
