Kai Luo 354d3106c6 [PowerPC] Skip combining (uint_to_fp x) if x is not simple type ...

Current powerpc64le backend hits
```
Combining: t7: f64 = uint_to_fp t6
llc: llvm-project/llvm/include/llvm/CodeGen/ValueTypes.h:291: llvm::MVT llvm::EVT::getSimpleVT() const: Assertion `isSimple() && "Expected a SimpleValueType!"' failed.
```
This patch fixes it by skipping combination if `t6` is not simple type.
