Shouldn't these checks be ASSERTs instead?
What does it mean if the size is negative or not a multiple of the entry size?

It's just invalid data then. The length field is tells how many ints we have
which describe the function data, and each function takes FunctionEntry::kSize
ints. So if the length is not non-negative multiple of FunctionEntry::kSize, the
data is wrong.

+    if (functions_size % FunctionEntry::kSize != 0) return 0;
+    return functions_size / FunctionEntry::kSize;

   // The following functions should only be called if SanityCheck has
   // returned true.
