Improving string::find such that it ultimately gets converted to calls to memchr and memcmp. This is an intermediate patch to see if there is an interest
in this optimization. I'm planning to propagate this change to similar functions string::rfind ... etc.

Worked in collaboration with Sebastian Pop.
