[PATCH] libcxx + MingW: correct printout of long doubles

[Yaron Keren]

The patch is required for target -mingw32 only since then clang makes 80
bit long doubles but not for target -win since clang behaves like Visual
C++ and produces 64 bit long doubles.

So this got me thinking, where libcxx on Windows is heading -
target -mingw32 with MingW32 headers and 80 bit long doubles?
target -win with Visual C++ headers with 64 bit long doubles?
both?
