Jinsong Ji eaf6746db0 [PowerPC] Add missing pattern for VSX Scalar Negative Multiply-Subtract Single Precision 
Summary:
This was found during review of https://reviews.llvm.org/D66050.
In the simple test of fdiv, we miss to fold
```
        fneg 2, 2
        xsmaddasp 3, 2, 0
```
to
```
        xsnmsubasp 3, 2, 0
```
We have the patterns for Double Precision and vectors, just missing
Single Precision, the patch add that.
