Upgrade MingW-w64 distributions for windows

This is the second part of splitting up #9218 (closed).

The goal is to move GHC x86 from MingW to MingW-w64 and to upgrade both the x86 and the x86_64 toolchains shipped with GHC to newer versions.

changed weight to 5

added Ttask Trac import labels

Chosen MinGW-w64 build for this are the dongsheng daily builds from the MinGW-w64 repository. Which avoids the issues mentioned in #9014 (closed) .

The GCC versions will be upgraded to 5.1.1.

To be complete the dongsheng builds contain:

binutils 2.25
gdb 7.9.1
make 4.1
gmp 6.0.0
mpfr 3.1.3
mpc 1.0.3
isl 0.14.1
mingw-w64 master
gcc 5.1.1

Could we, perhaps, use Msys2 builds for this? They are of a high quality and pretty well supported. Also they have gcc-5.2 and, most important, recently released binutils-2.25.1 which have a very important bug (wrong linking of 64-bit import libraries generated by MS linker) fixed.

As of today the transitive closure of packages required is (I believe) this:

mingw-w64-x86_64-crt-git-5.0.0.4531.49c7046-1
mingw-w64-x86_64-winpthreads-git-5.0.0.4538.78dca70-1
mingw-w64-x86_64-headers-git-5.0.0.4531.49c7046-1
mingw-w64-x86_64-libwinpthread-git-5.0.0.4538.78dca70-1
mingw-w64-x86_64-zlib-1.2.8-8
mingw-w64-x86_64-isl-0.14.1-2
mingw-w64-x86_64-mpc-1.0.3-2
mingw-w64-x86_64-mpfr-3.1.3.p0-2
mingw-w64-x86_64-gmp-6.0.0-3
mingw-w64-x86_64-gcc-libs-5.2.0-3
mingw-w64-x86_64-binutils-2.25.1-1
mingw-w64-x86_64-libiconv-1.14-5
mingw-w64-x86_64-gcc-5.2.0-3

The new repo of Msys2 packages is http://repo.msys2.org/mingw.

I have no problems with that. I'll try to modify the script tomorrow and let validate run over night.

I will keep them all separate packages and download each individually. I think that gives us a bit more control over updating the packages. Unless you think we should group them in one large tar file?

I've updated the toolchains to 5.2.0. Validate on x86_64 looks good again, still fixing a few tests on x86. See Phabricator.

Replying to [ticket:10726#comment:103382 awson]:

recently released binutils-2.25.1 which have a very important bug (wrong linking of 64-bit import libraries generated by MS linker) fixed.

Strictly speaking, binutils-2.25.1 doesn't have this bug fixed, but its MSys2 build *has* the relevant patch (and a couple of other useful patches) applied.
