elf: Optimize symbol binding by pre-computing divisions
The division for the hash table lookup shows up in profiles. We can
use a standard compiler optimization technique to speed up the hash
table lookup. The speedup is most pronounced when a symbol lookup
succeeds early in the scope array, otherwise the bitmap check
dominates the profiles.
