Hold dex caches live in class table
Prevents temporary dex caches being unloaded for the same dex file.
Usually this is OK, but if someone resolved a string in that dex
cache, it could leave stale pointers in BSS. Also it can use extra
memory in linear alloc if we allocate dex cache arrays multiple
times.

Record foreign dex files loaded by the app in the profile
A foreign dex file is a file which is not owned by the app
(it's not part of its code paths or its private data directory).
When such a dex file is loaded by the app, the runtime will record
a marker in a dedicated profile folder (foreing_dex_profile_path).
The marker is just a file named after the canonical location of the
dex file where '/' is replaced by '@'.
The markers will be used by the system server system server to
decide if the apk should be fully or profile guide compiled.

Save profile information in a separate thread.
Previously we would save the profiling information only when the app

Pass down to the runtime the application code paths.
When registering the app with the runtime the framework needs to pass
down the list of application code paths. This will be used by JIT to
know what profile info to persist.
This fixes the reliance on OatFileManager::GetPrimaryOatFile which may
produce inconsistent results based on external factors (i.e. class path
order or failing to compile the first dex file from the class path)

Change dex caches to be weak roots
Changed dex caches to be weak roots. This is necessary for class
unloading since the resolved types arrays would keep classes live
when they should be unloaded. Currently the dex caches still don't
get freed due to the class loader roots.
Also deleted some unused functionality in image writer.

Refactor and improve GC root handling
Changed GcRoot to use compressed references. Changed root visiting to
use virtual functions instead of function pointers. Changed root visting
interface to be an array of roots instead of a single root at a time.
Added buffered root marking helper to avoid dispatch overhead.
Root marking seems a bit faster on EvaluateAndApplyChanges due to batch
marking. Pause times unaffected.
Mips64 is untested but might work, maybe.

Add heap task processor
The heap task processor processes async tasks which may be delayed.
The motivation for this change is preventing deadlocks which
can occur when the daemon threads get suspended by GetThreadStack.
Other improvements, reduces daemon thread count by one.
Cleaner pending transition VS heap trimming logic.

Instruction set features for ARM64, MIPS and X86.
Also, refactor how feature strings are handled so they are additive or
subtractive.
Make MIPS have features for FPU 32-bit and MIPS v2. Use in the quick compiler

Some optimizations for the array alloc path.
- Force Array::Alloc() to be inlined.
- Simplify the array size overflow check.
- Turn fill_usable into a template parameter.
- Remove a branch in Array::DataOffset() and avoid
Primitive::ComponentSize(), which has a switch, in the array alloc
path.
- Strength reductions in the array size computation by using component
size shifts instead of component sizes. Store component size shift
in the upper 16 bits of primitive_type field.
- Speedup: ~4% (3435->3284) in MemAllocTest on N4.

Compile time performance improvements focusing on interpret-only.
Reduce virtual method dispatch in the method verifier and make more code
inline-able.
Add a StringPiece with const char* equality operator to avoid redundant
StringPieces and strlens.
Remove back link from register line to verifier and pass as argument to reduce
size of RegisterLine.
Remove instruction length from instruction flags and compute from the
instruction, again to reduce size.
Add suspend checks to resolve and verify to allow for more easy monitor
inflation and reduce contention on Locks::thread_list_suspend_thread_lock_.
Change ThrowEarlierClassFailure to throw pre-allocated exception.
Avoid calls to Thread::Current() by passing self.
Template specialize IsValidClassName.
Make ANR reporting with SIGQUIT run using checkpoints rather than suspending
all threads. This makes the stack/lock analysis less lock error prone.
Extra Barrier assertions and condition variable time out is now returned as a
boolean both from Barrier and ConditionVariable::Wait.

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.

Make allocations report usable size.
Work-in-progress to allow arrays to fill usable size. Bug: 13028925.
Use C++11's override keyword on GCC >= 2.7 to ensure that we override GC and
allocator methods.
Move initial mirror::Class set up into a Functor so that all allocated objects
have non-zero sizes. Use this property to assert that all objects are never
larger than their usable size.
Other bits of GC related clean-up, missing initialization, missing use of
const, hot methods in .cc files, "unimplemented" functions that fail at
runtime in header files, reducing header file includes, move valgrind's space
into its own files, reduce number of array allocation routines.

Avoid std::string allocations for finding an array class.
Introduce ClassLinker::FindArrayClass which performs an array class lookup
given the element/component class. This has a 16 element cache of recently
looked up arrays.
Pass the current thread to ClassLinker Find .. Class routines to avoid calls
to Thread::Current().
Avoid some uses of FindClass in the debugger where WellKnownClasses is a
faster and more compacting GC friendly alternative.

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.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.

Remove intialized static storage from dex cache.
The initialized static storage array is used by compiled code to determine if
for a sget/sput class initialization is necessary. The compiled code typically
doesn't require this test as the class is pre-initialized or the class being
accessed is the same as the current method.

Add sampling profiler
This adds a sampling profiler thread that runs every so often, gathering
profiling data and writing the results to a file in /data/data (specific to
app running). The intention is to use these files as input to the compiler

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..

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.
