kortschak 9baf9959f7 graph/path: add benchmarks for Dominators
The initial test cases are from Robin Eklind's decomp project, the DOT
files were generated using his instructions:

    git clone https://github.com/decomp/testdata
    go get github.com/decomp/decomp/cmd/ll2dot
    cd testdata/pathological/testdata
    ll2dot *.ll

..

DOT files placed in this directory will be used to run benchmarks on the
path.Dominators function. The DOT files included should contain one node
that has the label "entry" or "root". This node will be used as the control
flow entry point to the graph.
