Write conflict tables in image
Add image sections for runtime methods and conflict tables. This
makes it that we do not need to fake up a length prefixed array
for runtime methods.
Reduces .art private dirty and PSS.
System wide .art PSS goes from 32.5MB to 30.5MB after system boot.
Business card .art private dirty goes from 588K to 504K.
Increases image size by ~100K.
