MinGW-w64 project provides compilers for both Win32 and Win64 but only
defines the same __MINGW32__ symbol for the former as MinGW32 toolchain
which is quite different (notably doesn't provide many SDK headers that
MinGW-w64 does include). So we define a separate symbol which, unlike the
predefined __MINGW64__, can be used to detect this toolchain in both 32 and
64 bit builds.
And define __MINGW32_TOOLCHAIN__ for consistency and also because it's
convenient as we often want to have some workarounds only for the (old)
MinGW32 but not (newer) MinGW-w64, which still predefines __MINGW32__.
