Fixed cross compilation with mingw.

Tested in Mozilla source tree. I tried to use skia build system, but it's up to the task for cross compilation.

SkHRESULT.cpp - Use proper file name (that matters on case sensitive OSes)

SkAtomics_win.h - Don't use pragma intrinsic on GCC (this causes massive warnings)

SkOSFile_win.cpp - This one is tricky. GCC doesn't allow (void*) casts in template argument constants and INVALID_HANDLE_VALUE looks like this:
((HANDLE)(LONG_PTR)-1)
where HANDLE is typedefed to void*. Changed the code to use LONG_PTR as template argument and cast it when needed.
