46b4ca8e - [NFC][PowerPC] Pre-commit testcases for locking down the xxsel instructions for ternary patterns (#146764)

[NFC][PowerPC] Pre-commit testcases for locking down the xxsel instructions for ternary patterns (#146764) Pre-commit test case for exploitation of `xxsel` for ternary operations of the pattern. This adds support for `v4i32`, `v2i64`, `v16i8` and `v8i16` operand types for the following patterns. ``` ternary(A, X, and(B,C)) ternary(A, X, B) ternary(A, X, C) ternary(A, X, xor(B,C)) ternary(A,X,or(B,C)) ``` Exploitation of xxeval to be added later.
