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)

Add hash map, reduce excessive hashing
Changed the class def index to use a HashMap instead of unordered_map
so that we can use FindWithHash to reduce how often we need to compute
hashes.
Fixed a bug in ClassLinker::UpdateClass where we didn't properly
handle classes with the same descriptor but different class loaders.
Introduced by previous CL.

Make use of profiling information for dex2oat
If the profile file exists, the compiler driver will read it
and store the data in an internal map. Then, when we want to work
out whether to compile a method or not, the map is consulted and if
the method shows up with a high enough percentage of use we compile it.
The profile file itself is created by installd and is writeable by the
app. The file is in /data/dalvik-cache/profiles and is named by
the package name.
This also modifies the profiler itself to:
1. Only count runnable threads (not suspended threads) in the profile
2. Use system properties to allow tuning of the profile parameters
3. Merge profiles from multiple processes using file locking.

Avoid marking old class linker and intern table roots during pause.
The new root visiting logic has a concept of a root log which holds
new roots which were added since the start of the GC. This is an
optimization since it lets us only mark these newly added roots
during the pause (or pre-cleaning) since the other roots intern table
and class linker roots were marked concurrently at the start of the
GC.
Before (EvaluateAndApplyChanges):
MarkConcurrentRoots: Sum: 605.193ms
After:
MarkConcurrentRoots: Sum: 271.858ms
This should also reduce pathological GC pauses which used to be able
to happen when the intern table or class linker became "dirty"
during the concurrent GC.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.

Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the

Compacting collector.
The compacting collector is currently similar to semispace. It works by
copying objects back and forth between two bump pointer spaces. There
are types of objects which are "non-movable" due to current runtime
limitations. These are Classes, Methods, and Fields.
Bump pointer spaces are a new type of continuous alloc space which have
no lock in the allocation code path. When you allocate from these it uses
atomic operations to increase an index. Traversing the objects in the bump
pointer space relies on Object::SizeOf matching the allocated size exactly.
Runtime changes:
JNI::GetArrayElements returns copies objects if you attempt to get the
backing data of a movable array. For GetArrayElementsCritical, we return
direct backing storage for any types of arrays, but temporarily disable
the GC until the critical region is completed.
Added a new runtime call called VisitObjects, this is used in place of
the old pattern which was flushing the allocation stack and walking
the bitmaps.
Changed image writer to be compaction safe and use object monitor word
for forwarding addresses.
Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc..
TODO: Enable switching allocators, compacting on background, etc..

Fast JNI support.
Use a modifier to signal a native method is a fast JNI method. If the
modifier is set then don't perform runnable transitions.

Remove four counter increments out of the allocation path.
- This change removes the four allocation counters (the number of
bytes allocated, the number of objects allocated, the number of bytes
allocated ever, the number of objects allocated ever) from the
dlmalloc space allocation path. Now those counter values are computed
on the fly based on a combination of the two new counters that are
incremented by the GC side (the number of bytes freed ever and the
number of objects freed ever) and mspace_inspect_all() calls.
- This results in a 1-2% speedup (though with some noise) in Ritz
MemAllocTest on Nexus 4.

Handle OOMEs in class linker with grace.
Check for OOMEs and then fail due to them in class loading.
Make the compiler driver spot OOMEs during resolution and abort compilation to
avoid needless GC thrash then eventual death.
Allocate the pre-allocated OOME during Runtime::Init as Runtime::Start isn't
called in the context of the compiler/tools.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.

Use JNI to access activity manager process state.
After a GC occurs, we use JNI to access activity manager process
state to decide whether or not we will trim.

Add interface for updating the heap's process state

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
