changed regular allocator to MallocMC

 - seems to segfault on some occasions :(
Benchmark runs half-way

 - ok with 128 Threads
 - unspecified launch failure with 256 Threads (both regular allocator
   and mallocMC)
squashed some nasty bug

 - mallocMC works well up to 16384 Threads (not tested more)
benchmark running ok

 - lots of continous mallocs
 - same number of frees
 - no crashes
 - mostly enough memory available
 - no SIMD optimizations
debugging the problem of lost slots
submodule updated
Benchmark running successfully
Added more compilation targets
adjusted HeapSize
better configuration for the benchmark
benchmark has now good output

 - multiple loops for more simulations
 - still needs the appropriate command line parameters
added more logic for the benchmarking loop
did a first benchmark with mallocMC log-scale
added --device option
