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.

Relocate DWARF using .oat_patches. The current solution is to hard-code knowledge of DWARF in the linker. This works for simple use of DWARF, but breaks as soon as I try to do anything more complex. Making the linker fully support DWARF would be non-trivial task and would be essentially rewrite. Using .oat_patches is much easier solution. Relocating .debug_* sections required extending .oat_patches to support more sections than just .text. I have encoded each section as null-terminated section name followed by ULEB128 deltas. The ULEB128 encoding shrinks .oat_patches for .text by factor of about 6 with 64-bit compiler, and factor of 3 with 32-bit compiler. On the other hand, it grows by the extra .oat_patches for DWARF which were not present before (if debug symbols are included). Overall, it is still a clear improvement even with the DWARF patches.

Runtime can now be set to require relocation Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force the runtime to require that all files that are run are relocated, to prevent attacks based on the known art base address. Add support for running patchoat on oat files compiled without an image. Change run-test to have new --prebuild and --relocate flags.

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.
