Don't assume that __MINGW32__ implies x86; Windows runs on ARM/ARM64
as well, and there are mingw toolchains that target those architectures.

This mirrors how the MSVC parts of the same expressions are written,
as (defined(_WIN32) && defined(_M_IX86)) and
(defined(_WIN64) && defined(_M_X64)) - not relying on _WIN32/_WIN64
or __MINGW32__/__MINGW64__ alone to indicate architecture.

Change the __MINGW64__ and _WIN64 ifdefs into plain __MINGW32__
and _WIN32 as well, for clarity - these defines mostly imply
platform.
