This function could use from a more descript name. Below are some suggestions:
```suggestion
static unsigned getScalarOrVectorByteSize(llvm::Type *Ty) {
```
```suggestion
static unsigned getScalarOrVectorStorageSize(llvm::Type *Ty) {
```
```suggestion
static unsigned getScalarOrVectorMemorySize(llvm::Type *Ty) {
```
