This patch is based on __strcmp_power10.
Improvements from __strncmp_power9:
1. Uses new POWER10 instructions
- This code uses lxvp to decrease contention on load
by loading 32 bytes per instruction.
2. Performance implication
- This version has around 38% better performance on average.
- Minor performance regression is seen for few small sizes
and specific combination of alignments.
