Limit the size of pc2pc debug-info encoding.

This CL introduces pc2pc encoding points such that a given set of
methods is bounded by an expansion/non-sharing threshold.
The default value is 200.000 which is found to have very little
impact on size and avoids most regression time in dex2oat
speed-profile compilations.

For experimental purposes the defaults can be adjusted with:
 -Dcom.android.tools.r8.pc2pcOverheadThreshold=100000
