[PATCH] D45571: [ELF] - Speedup MergeInputSection::splitStrings

I believe a fast strlen() can be implemented using SSE instructions. And if you are using SSE instructions, your data is loaded to XMM registers. I believe there exists a fast vectorized hash function that works on data on a XMM register. I wonder if we can combine the two to create a single fast function that returns the length of a string as well as its hash value.
