Fix compilation with MinGW-w64

Fix compilation with MinGW-w64 with the following changes:
- Include intrin.h to fix __cpuid not declared error
- Include intrin.h before *mmintrin.h headers to avoid extern linkable
  mismatch
- Use quintptr instead of unsigned long to handle LLP64
- Do not declare winuser.h structs already provided with MinGW-w64
- Work around IID_IShellItem being declared but not defined with
  MinGW-w64
- Remove incorrect use of SUCCEEDED macro on pointer
