Subject: PATCH: Improve 64 bit strchr and strrchr functions for atom (withSSE2 but without using bsf, bsr)

Hello,

This patch improves strchr and strrchr functions on atom for 64 bit
mode (uses SSE2 but without using bsf, bsr instructions).

It improves performance by up to 3X for strchr and strrchr on atom.
