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. Change-Id: I898b7c711979447d4756b3f7b567c49a8d33187b
