Write conflict tables in image
Add image sections for runtime methods and conflict tables. This
makes it that we do not need to fake up a length prefixed array
for runtime methods.
Reduces .art private dirty and PSS.
System wide .art PSS goes from 32.5MB to 30.5MB after system boot.
Business card .art private dirty goes from 588K to 504K.
Increases image size by ~100K.

Fix up dex cache strings stored in classes
Previously we left the image pointer instead of fixing up the pointer
to the one in the BSS. This only showed up because JIT does the same
as boot image, bypassing null check.
Fixed a bug where oat files without embedded dex cache arrays would
get their dex cache arrays corrupted.
Added a non virtual class visitor for performance.

Add support for LZ4 compressed image files
Added dex2oat option --image-format=(store|lz4). Using lz4 means
that the main image section (all data other than header and bitmap)
are stored in a compressed state.
N5 results:
Boot image size: 8067128 -> 2827605
Decompression time 18.93ms
Decompression rate: 426MB/s
Patchoat is not currently supported since it maps the source image
directly. In order to support compressed images we would need to
recompress the output image and then write it back out to a file.
Also there are not many cases where we would want to patch a
compressed image since they are going to be dirty memory when
uncompressed anyways. Might as well just patch as we are loading.

Reduce memory used by CompiledMethods.
Use LengthPrefixedArray<>s instead of SwapVector<>s to store
CompiledMethod data and get rid of the unnecessary members
of CompiledMethod to reduce dex2oat memory usage. Refactor
the deduplication from CompilerDriver to a new class.
Use HashSet<> instead of std::set<> for the DedupeSet<> to
further decrease the memory usage and improve performance.
This reduces the dex2oat memory usage when compiling boot
image on Nexus 5 (with Optimizing, -j1) by ~6.75MiB (5%).
This also reduces the compile time by ~2.2% (~1.6% dex2oat
time; with Optimizing, without -j).

ART: Compress LengthPrefixedArray on 32-bit targets.
Previously, the LengthPrefixedArray<ArtMethod> on 32-bit
targets contained a 64-bit length field followed by the
ArtMethod elements with size only a multiple of 4, not 8.
Consequently, an odd-length array broke the alignment for
the following array which would have the 64-bit length
placed at an unaligned address.
To fix that, we make the length field 32-bit and explicitly
pass the alignment information to the LengthPrefixedArray.
This also makes the 32-bit boot image a bit smaller.
On Nexus 5, AOSP, ToT, the field section is 11528B smaller
and the method section is 21036B smaller. 64-bit targets
should see the same savings for the field section but no
difference for the methods section.

Change 64 bit ArtMethod fields to be pointer sized
Changed the 64 bit entrypoint and gc map fields in ArtMethod to be
pointer sized. This saves a large amount of memory on 32 bit systems.
Reduces ArtMethod size by 16 bytes on 32 bit.
Total number of ArtMethod on low memory mako: 169957
Image size: 49203 methods -> 787248 image size reduction.
Zygote space size: 1070 methods -> 17120 size reduction.
App methods: ~120k -> 2 MB savings.
Savings per app on low memory mako: 125K+ per app
(less active apps -> more image methods per app).
Savings depend on how often the shared methods are on dirty pages vs
shared.
TODO in another CL, delete gc map field from ArtMethod since we
should be able to get it from the Oat method header.

ART: Add support for patching and loading OAT files compiled with PIC
* Images (.art) compiled with pic now have a new field added.
* isDexOptNeeded will now skip patch-ing for apps compiled PIC
* First-boot patching now only copies boot.art, boot.oat is linked
As a result, all system preopted dex files (with --compile-pic) no
longer take up any space in /data/dalvik-cache/<isa>.

Optimize method linking
Added more inlining, removed imt array allocation and replaced it
with a handle scope. Removed some un-necessary handle scopes.
Added logic to base interface method tables from the superclass so
that we dont need to reconstruct for every interface (large win).

Simplify instance reference offsets.
Don't encode Object's class. Use trailing rather than leading zeroes to give
offset position.

Add patchoat tool to Art.
Add a new executable called patchoat to art. This tool takes already
compiled images and oat files and changes their base address, acting as
a cheap form of relocation.
Add a --include-patch-information flag to dex2oat and code to add
required patch information to oat files created with the quick compiler.

Remove oat file location in the image.
The oat file is now always in the same directory, and has the
same name as the image file. Only difference is the extension.
This also removes the need for host-prefix.

Write out image bitmap inside of image file.
We now create the image bitmap when we generate the image. The image
bitmap is written after the image inside of the image file. This
speeds up dex2oat by making walking the image during heap creation
unnecessary. This should also help memory pressure by enabling the
image bitmap to be swappable.

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.
