Dokyung Song 1bb1eac6b1 [libFuzzer] Add a command-line option for tracing mutation of corpus inputs in the dot graph format. 
This patch adds a new command-line option -mutation_graph_file=FILE for
debugging purposes, which traces how corpus inputs evolve during a fuzzing
run. For each new input that is added to the corpus, a new vertex corresponding
to the added input, as well as a new edge that connects its base input to itself
are written to the given file. Each vertex is labeled with the filename of the
input, and each edge is labeled with the mutation sequence that led to the input
w.r.t. its base input.

The format of the mutation graph file is the dot file format. Once prepended and
appended with "graph {" and "}", respectively, the graph becomes a valid dot
file and can be visualized.
