ARMv8: Update qHash for strings to use the CRC32 instruction
Same as the SSE4.2 implementation: use the (optional) ARMv8 crc32[bhwd]
instruction to calculate hashes for strings. For Aarch64, support for
the instruction is dynamically detected. For a 32bit ARM binary, dynamic
detection is only done when the compiler is explicitly told to target
ARMv8. When telling the compiler to target an other/older version, the
crc32 code is not compiled.
