since most of the code is same as
`DefaultABIInfo::classifyArgumentType(QualType Ty)` , I suggest rewrite the
function `PPC32_SVR4_ABIInfo::classifyArgumentType` as
```
ABIArgInfo PPC32_SVR4_ABIInfo::classifyArgumentType(QualType Ty,
int &ArgGPRsLeft) const {
....
special functionality code of the function here
.....
DefaultABIInfo::classifyArgumentType(Ty)
}
```
duplication code is not a good idea.
