c3e7a1ab - [NFC][PowerPC] Optimize vector compares for not equal to non zero vectors (#171635)

[NFC][PowerPC] Optimize vector compares for not equal to non zero vectors (#171635) Lockdown instructions for vector compares `not equal to non-zero (Ex: vec[i]!=7)`. Current implementation can be made better by removing the negation and using the identity ``` 0XFFFF + 1 = 0 and 0 + 1 = 0 ``` Co-authored-by: himadhith <himadhith.v@ibm.com>
