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

The test results are interesting

The geometric mean for seconds-elapsed improves by 0.5%. Scylla is just 0.3% faster.

Part of the reason is a 12% regression on the number of instructions for scylla. Maybe that is because xxhash64 hashes 8 bytes at a time? Have you experimented with reading 8 bytes at a time?
