powerpc: Optimized rawmemchr for POWER9
This version uses vector instructions and is up to 60% faster on medium
matches and up to 90% faster on long matches, compared to the POWER7
version. A few examples:
__rawmemchr_power9 __rawmemchr_power7
Length 32, alignment 0: 2.27566 3.77765
Length 64, alignment 2: 2.46231 3.51064
Length 1024, alignment 0: 17.3059 32.6678
