    auto incoming = map_range(PHI->incoming_values(), [](Use *X) {return X;});
```
gives the following error, under gcc 7.5 : 
```
In file included from {...snip...}

                     ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
```
Expected behavior: 
1. I get range from `->incoming_values()`
2. I use it like normal with whatever function takes an llvm range

Actual behavior: 
1. I get a "wannabe range that doesnt work properly"
2. can't use it in any way as a range...

The [docs](https://llvm.org/doxygen/classllvm_1_1PHINode.html#a1f0ff79b64a40d383b891f1baba89c6b) say that it should return a range...
