Add an option to enable collecting dex pc in ART profiler
This CL allows the ART profiler to collect both method signature and
dex pc. The type of the profile data is controlled by the option
"-Xprofile-type:{method,dexpc}". To avoid conflicting with the
original profile data based on method signatures, the new profile
data are stored in files with extension ".pc".
