Add patchoat tool to Art.
Add a new executable called patchoat to art. This tool takes already
compiled images and oat files and changes their base address, acting as
a cheap form of relocation.
Add a --include-patch-information flag to dex2oat and code to add
required patch information to oat files created with the quick compiler.
