compile errors with toolset LLVM for Visual Studio 2017 (LLVM_v141)

[StanPepels]

Hey, I was trying to compile bullet with visual studio 2017 with toolset " LLVM for Visual Studio 2017 (LLVM_v141)" (set via CMake) when I ran into the following compile error.

btScalar.h(325,16): error : overloaded 'operator+' must have at least one parameter of class or enumeration type btScalar.h(330,16): error : overloaded 'operator-' must have at least one parameter of class or enumeration type

I Tried commenting out the operator overloads (issue here is that _m128 is not a user defined type) which brought me to the following

I Attempted to fix those as well and managed to get some of the fixes but in the end I couldn't find a solution. I'm not very knowledgeable about the code thats breaking (seems like something with regards to intrinsics?) I checked the declerations of the functions and they seem to be defind in <intrin.h> which is included.

Maybe i'm missing something obvious?
