ARM optimized insert_string

Using a faster hash function yields a considerable performance boost
in compression (average 8% on A53 and 24% on A72).

This change was enabled by previous patch with optimized crc32 using
ARMv8-1 crypto extensions for performing CPU feature detection
(so won't help older ARMv7 SoCs).
