Print more info in MarkSweep::VerifyRoot
Refactored old root callback to use a new class called RootInfo.
RootInfo contains all the relevant info related to the root
associated with the callback. The MarkSweep::VerifyRoot function
now uses this info to print the StackVisitor's described location
if the GC root is of the type kRootJavaFrame.
Some other cleanup.
Example output:
E/art (12167): Tried to mark 0x123 not contained by any spaces
E/art (12167): Attempting see if it's a bad root
E/art (12167): Found invalid root: 0x123 with type RootJavaFrame
E/art (12167): Location=Visiting method
'void java.lang.Runtime.gc()' at dex PC 0xffffffff (native PC 0x0)
vreg=0

Disable adding main and non moving spaces to immune region in GSS
Disabled adding the main and non moving space to the immune region.
This will enable us to recycle bump pointer spaces for malloc space
-> malloc space compaction as well as collector transitions.
Also added logic for falling back to the non moving space, we may
copy objects there.
Refactored mod union table logic into MarkReachableObjects.
No measurable performance benefit or regression.

Improve performance of invokevirtual/invokeinterface with embedded imt/vtable
Add an embedded version of imt/vtable into class object. Both tables start at
fixed offset within class object so method/entry point can be loaded directly
from class object for invokeinterface/invokevirtual.

Improve heap verification for invalid roots.
The new root verification prints the root type and owner thread id as
well as the type of the object.
Also a bit of work for planned multi-threaded verification.

Change ProcessReferences to not use RecursiveMarkObject.
Calling ProcessMarkStack in RecursiveMarkObject caused a lot of
overhead due to timing logger splits. Changed the logic to be the
same as prior to the reference queue refactoring which involves
calling process mark stack after preserving soft references and
enqueueing finalizer references.
FinalizingGC longest pause is reduced by around 1/2 down to ~300ms.
Benchmark score ~400000 -> ~600000.
Also changed the timing logger splits in the GC to have (Paused) if
the split is a paused part of the GC.

Change root visitor to use Object**.
Simplifies code and improves the performance of root visiting since
