Ensure void type is resolved when running without image
To initialize java.lang.Void correctly, we need to ensure the 'void'
class is initialized in the dex cache of core-libart (because Java
code relies on it). However, if we run without image, the dex cache
may not contain the void class before we initialize java.lang.Void
class.
This CL fixes this by forcing the resolution of 'void' class when
initializing the runtime without image.
We also generalize that to other types by not skipping verification
when running with preopted oat files without image. By verifying
all classes, we ensure all resolved types are in the dex caches.

JDWP: only deoptimize when it is required
We don't need to deoptimize anything when we forced the use of the
interpreter (-Xint). In this case, no compiled code is executed
(except native methods which are not concerned by deoptimization).
Therefore we even don't need to enable/disable deoptimization support
in instrumentation.
We also don't need to deoptimize a method that hasn't been compiled.
Since it will run with interpreter, there is no point deoptimizing
it. However this method may be inlined in a compiled caller method
so we still need to deoptimize everything in this case.
This CL updates breakpoint support by storing the required kind of
deoptimization for a particular method. There are 3 cases:
- kNothing: the method does not require deoptimization.
- kSelectiveDeoptimization: the method needs to be deoptimized.
- kFullDeoptimization: we must deoptimize everythinig.
When uninstalling a breakpoint, we need to do the reverse operation.
Also fixes the SanityCheckExistingBreakpoints function to control
breakpoints related to the given method only and adds extra verbose
ilogs when choosing the appropriate deoptimization kind.
Includes a partial cherry-pick of commit
87553c9fa1298ffb40127b2bb6413859fd3f79df to use method

dex2oat: Pack likely-dirty objects together when generating the boot image
This introduces a new algorithm into image writer which "bins" objects
by how likely they are to be dirtied at runtime. Objects in the same bin
are placed contiguously in memory (i.e. into the same page). We try to
tune the bin selection based on how clean or how dirty the object will
likely be at runtime.
As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in
zygote (shared-dirty).
There is still about 800KB of objects that are clean but located in
dirty pages, so with more analysis we can tune the bin selection and get
even more memory savings.
