The code is identical, I did not change anything in the GC code. So it 
uses whatever code comes with the MinGW GDC 2.058 release.

The problem with intstrumentation is, that I can not recompile druntime 
for the MinGW GDC, as this is not possible with the binary release of 
MinGW GDC and I did not go thorugh the effort to setup the whole build.
I'm open to suggestions though how I could profile the GC without 
recompiling druntime. If someone else wants to profile this, I can also 
provide precompiled versions of both versions.
