Improvements and clustering for the .dot file generation.

Dot clusters are used to show SEA IR regions.
Passing around dex_file for improved instruction  text representation.
SeaGraph now stores the dex file.
Removed all .dot edges except ssa edges and inter-region control flow.
Changed color to gray for ssa edges and kept black for control flow.
Consistently labeled SSA edges with virtual register number.
Replaced stringstream with StringPrintf.
