It seems that the code will get another assertion failed if `-` is changed to `+` on line 5:
Assertion `getType()->isIntOrIntVectorTy() && "Tried to create an integer operation on a non-integer type!"' failed.`

Attempting to compile the following program with Clang Trunk and Clang Assertion Trunk:
```c
typedef unsigned __int128 __attribute__ ((__vector_size__ (64))) v512u128;
v512u128 f;
void foo(_Complex double e) {
v512u128 g = f - -e;
}
```
