 Partial insertion sort the order of elements returned by std::partition is implementation defined (since not stable) and could depend on the version of libstdc++ linked. 
As std::stable_partition was tested to be too slow (http://tests.stockfishchess.org/tests/view/585cdfd00ebc5903140c6082). 
Instead combine partition with our custom implementation of insert_sort, which fixes this issue. 
Implementation based on a patch by mstembera (http://tests.stockfishchess.org/tests/view/58d4d3460ebc59035df3315c), which suggests some benefit by itself. 
Higher depth moves are all sorted (INT_MIN version), as in current master.
