There are a few things that I wanted to reorganize for a while: - the loop that incrementally goes through classes on failure looked horrible in assembly, mostly because of `LIKELY`/`UNLIKELY` within the loop. So remove those, we are already in an unlikely scenario - hooks are not used by default on Android/Fuchsia/etc so mark the tests for the existence of the weak functions as unlikely - mark of couple of conditions as likely/unlikely - in `reallocate`, the old size was computed again while we already have it in a variable. So just use the one we have. - remove the bitwise AND trick and use a logical AND, that has one less test by using a purposeful underflow when `Size` is 0 (I actually looked at the assembly of the previous code to steal that trick) - move the read of the options closer to where they are used, mark them as `const` Overall this makes things a tiny bit faster, but cleaner.
