Include arm_neon.h in mingw targeting ARM Windows.

Browse Source 
The llvm-mingw project includes cross-compilers targeting ARM: https://github.com/mstorsjo/llvm-mingw/releases

Currently, compilation fails with this configuration, because neon features are used as long as __ARM_NEON is defined, but arm_neon.h was not included.
