  [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.
