- This is necessary in order to compile AVX intrinsics correctly in
Visual Studio. Having everything in their own units should also make
compiling normal C code with optimizations on easier.
- For now the makefile still relies on GCC __target__ attribute for compiling
intrinsics.
- Enforces a little bit more hierarchy. Compilation units are in strategies
and whatever inline includes they have are in a folder with the same name
as the strategy.
