Relax annotation visibility so runtime includes build.
Previous behavior in M and earlier would allow annotations marked
VISIBILITY_BUILD to be visible to the runtime when they should not
have been. When targeting older sdks, revert to this behavior.

Write dex files to oat file early.
Write dex files to oat file before we actually open and
verify them. Instead, open and verify the copies from the
oat file and use these. This way, in the most common case
of zipped dex files, we have mmapped dex files instead of
inflated dex files. That reduces the number of dirty pages
used by dex2oat.
Reading /proc/self/statm after we write the oat file for
a compilation of a certain large app on Nexus 5 AOSP build
with -j1, three attempts before and after this CL gave
before: 346061 189462 6269 26 0 140723 0
346189 189450 6269 26 0 140851 0
346061 189463 6269 26 0 140723 0
after: 346186 185808 23040 27 0 140468 0
346186 185819 23040 27 0 140468 0
346186 185822 23040 27 0 140468 0
These values are in pages (4KiB), so while the "size"
(=VmSize) is essentially unchanged, the "resident" (=VmRSS)
is over 14MiB less and the "shared" (i.e. backed by a file)
is 65.5MiB more. That is, the amount of dirty non-pageable
memory used is reduced by about 80MiB.
The oat file format has changed slightly, the class offset
table has been moved from the OatDexFile to its own section.
This actually fixes the alignment of these offsets as they
could have been unaligned previously, yet accessed as normal
with significant performance impact if the kernel has to
emulate the unaligned access (say, mips).

Implementation of fast lookup table to search class_def by descriptor
Lookup table is a hash table which built at compile time and stored
into oat file. At runtime the table is restored and used in the
method DexFile::FindClassDef(const char*) to perform fast search of
the class_def_idx by class descriptor. Advantages of the lookup table
over the HashSet (runtime/base/hash_set.h) are:
1. Lookup table is built at compile time and uses read-only memory at
runtime
2. Lookup table uses less memory then DexFile::Index (less by 80% for
/system/framework/framework.jar on Nexus5)
3. Lookup table does less string comparisons compared with HashSet
(less by 70% for zygote process on Nexus5)
The disadvantage of the lookup table is it increased boot.oat size by
0.2% on Nexus5 and application .oat file by 0.3% in average on Nexus5.
mathieuc changes:
Create lookup table in dex2oat to speed up compilation. Clean up code
to follow style guide and use less static functions. Added
performance measurements.
Compile ~100 APKs 5 times with filter interpret-only:
Before:
real 1m8.989s
user 0m59.318s
sys 0m7.773s
After:
real 1m1.493s
user 0m52.055s
sys 0m7.581s
App launch (AOSP N5 maps, average of 45 runs):
Before: 966.84ms
After: 923.733ms
Launch speedup is 4.7%
Memory usage compared to HashSet index on 50 various APK:
32 bit: HashSet ~625694b vs TypeLookupTable ~404268b
64 bit: HashSet ~1251390b vs TypeLookupTable ~404268b

ART: Allow oat files with duplicates classes in corner case
When the oat file is actually an odex file, that is, a preopted
/system app, then it is impossible to fall back to the original
APK, as that has been stripped.
When it looks like it will be impossible to successfully open the
original dex location, grudgingly allow to open the found oat file,
even if it has duplicate classes, but warn accordingly.

ART: Simple structural class check
Adds a simple check to class-loading when the embedded dex file in
an oat file and the dex file on the class path where we found the
class do not match.
We require that the number of methods and fields do not change, as
that will almost certainly mean that quickened and other compiled
offsets are wrong now. This is a reasonably lightweight change, but
we should investigate a full comparison including name and type of
members.

Fix an Alloc setting to allow running valgrind.
Refactor the fault handler to manage (and correctly release) the
handlers.
Fix minor failure-case leaks exposed by tests.
Failing tests:
The optimizing compiler is leaking non-arena-ed structures
(e.g., assembler buffers), as code generators are not destroyed.
The solution has been moved to a follow-up CL.
Note: All 64b tests are failing as we cannot allocate a heap.

Improve dex location canonicalization-related performance.
Eagerly add canonical dex file locations to the OatFile's
primary lookup map in Setup(). This moves the boot.oat work
from every app startup to the zygote initialization. Since
we always ended up initializing the canonical location map
anyway due to the way that we're loading dex files, the lazy
initialization didn't save anything.
Clean up dex file name canonicalization to make sure we
free() the memory returned by realpath() rather than using
std::unique_ptr<> with the default deleter.
Avoid some unnecessary duplicate OatDexFile lookups.

ART: Native support for multidex
Native support for zip files with multiple classesX.dex.
Works by explicitly looking for those files in ascending order. As
these files have no file system representation for themselves,
introduce synthetic dex locations: the name of the originating file
plus a colon plus the name of the dex file, e.g., test.jar:classes2.dex.
Opening a zip dex file will return all dex files in this way. This
keeps the changes to dex2oat minimal.
To hide multidex/synthetic names from the Java layer, let the handle
of dalvik.system.DexFile refer to a vector of DexFile objects. When
opening a location, test possible synthetic names and add them to the
vector. Thus, the original multidex jar in the classpath will be
associated with all embedded dex files.

Fix debugger crash in native method frames.
The main crash happens when we try to read (StackFrame::GetValues) or write
(StackFrame::SetValues) values in native frames. We use the method's vmap to
know where Dalvik registers live but native methods don't have vmap. The fix
is to reply with the OPAQUE_FRAME error which indicates local values are not
accessible in the frame.
We prevent from dereferencing null code item which causes some crashes too.
This happens when we compute the line table (Method::LineTable) and variable
table (Method::VariableTable) of methods without code: native, proxy and
abstract methods. We do not expect to encounter abstract methods though. We
take care of these kinds of method when mangling/demangling local value slots.
We also fix the location's pc of native and proxy frames where it must be -1
(as 8-byte value). We'll use this property to detect such frames in the JDWP
tests.

Remove blacklist
Removes the class initialization blacklist and use transaction to detect and
revert class initialization attempting to invoke native method. This only
concerns class initialization happening at compilation time when generating an
image (like boot.art for the system).
In transactional mode, we log every object's field assignment and array update.
Therefore we're able to abort a transaction to restore values of fields and
array as they were before the transaction starts. We also log changes to the
intern string table so we can restore its state prior to transaction start.
Since transactional mode only happens at compilation time, we don't need to log
all these changes at runtime. In order to reduce the overhead of testing if
transactional mode is on/off, we templatize interfaces of mirror::Object and
mirror::Array, respectively responsible for setting a field and setting an
array element.
For various reasons, we skip some specific fields from transaction:
- Object's class and array's length must remain unchanged so garbage collector
can compute object's size.
- Immutable fields only set during class loading: list of fields, method,
dex caches, vtables, ... as all classes have been loaded and verified before a
transaction occurs.
- Object's monitor for performance reason.
Before generating the image, we browse the heap to collect objects that need to
be written into it. Since the heap may still holds references to unreachable
objects due to aborted transactions, we trigger one collection at the end of
the class preinitialization phase.
Since the transaction is held by the runtime and all compilation threads share
the same runtime, we need to ensure only one compilation thread has exclusive
access to the runtime. To workaround this issue, we force class initialization
phase to run with only one thread. Note this is only done when generating image
so application compilation is not impacted. This issue will be addressed in a
separate CL.

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.

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..

Introduce Signature type to avoid string comparisons.
Method resolution currently creates strings to then compare with strings formed
from methods in other dex files. The temporary strings are purely created for
the sake of comparisons. This change creates a new Signature type that
represents a method signature but not as a string. This type supports
comparisons and so can be used when searching for methods in resolution.
With this change malloc is no longer the hottest method during dex2oat (now its
memset) and allocations during verification have been reduced. The verifier is
commonly what is populating the dex cache for methods and fields not declared
in the dex file itself.
