Remove dependency on compiler driver for sharpening
and dex2dex (the methods called on the compiler driver were
doing unnecessary work), and remove the now unused methods
in compiler driver.
Also remove test that is now invalid, as sharpening always
succeeds.

Handle MarkInBoot image for LoadKind::kReferrersClass. This reduces
read barriers for the boot image if the referring class is in
the boot image.
Only really helps CC case, TODO avoid doing the work for non CC?

Concurrent copying baker:

Around 0.4% of 2.4% is from re-enabling kBootImageLinkTimeAddress,
kBootImageLinkTimePcRelative, and kBootImageAddress.

others with forward references and add includes to source
files as needed. Reduce dependency on stack.h by pulling
StackReference<> out to its own file.

Previously, the string dex cache was dex_file->NumStringIds() size, and
@ruhler found that only ~1% of that cache was ever getting filled. Since
many of these string dex caches were previously 100,000+ indices in
length, we're wasting a few hundred KB per app by storing null pointers.
The intent of this project was to reduce the space the string dex cache
is using, while not regressing on time that much. This is the first of a
few CLs, which implements the new fixed size array and disables the
compiled code so it always goes slow path. In four other CLs, I
implemented a "medium path" that regresses from the previous "fast path"
only a bit in assembly in the entrypoints. @vmarko will introduce new
compiled code in the future so that we ultimately won't be regressing on
time at all. Overall, space savings have been confirmed as on the order
of 100 KB per application.
A 4-5% slow down in art-opt on Golem, and no noticeable slow down in the
interpreter. The opt slow down should be diminished once the new
compiled code is introduced.

For classes in the boot image, use either direct pointers
or PC-relative addresses. For other classes, use PC-relative
access to the dex cache arrays for AOT and direct address of
the type's dex cache slot for JIT.
For aosp_flounder-userdebug:
- 32-bit boot.oat: -252KiB (-0.3%)
- 64-bit boot.oat: -412KiB (-0.4%)
- 32-bit dalvik cache total: -392KiB (-0.4%)
- 64-bit dalvik-cache total: -2312KiB (-1.0%)
(contains more files than the 32-bit dalvik cache)
For aosp_flounder-userdebug forced to compile PIC:

We still use ProfileInfo objects to record profile information. That
gives us the flexibility to add the inline caches in the future and the
convenience of the already implemented GC.
If UseJIT is false and SaveProfilingInfo true, we will only record the
ProfileInfo and never launch compilation tasks.

Do not look up the String for JIT, just check if it's in the
dex cache. Strings on hot paths should already be resolved
and we don't want to unnecessarily increase JIT compile time
to have a chance of improving a cold path.
Also, change the enum LinkerPatchType to be an inner enum
class of LinkerPatch and clean up casts between pointers and
uint64_t.

The compiler driver makes assumptions that don't hold for
the optimizing compiler, and will for example always go to
slow path for an invoke-super when there's no verified method.
Also fix GenerateInvokeVirtual in the presence of intrinsics.
Next change will address some of the TODOs in sharpening.cc.

Use this list to improve invoke-static/-direct dispatch for
intra-oat calls.
Also fix a latent ArmBaseRelativePatcher::ReserveSpaceEnd()
bug exposed by a buggy early version of this CL: when we
have unresolved patches at the end of all code, we need to
emit a final thunk. Though the OatWriter will try to patch
the unresolved call to a trampoline at the beginning of the
oat file, that trampoline may be too far and the relative
patcher doesn't know about it anyway, so it needs to assume
that a thunk is needed.
This reduces the overall size of oat files present in dalvik
cache on Nexus 9 after first boot by over 1MiB, AOSP ToT,
aosp_flounder-userdebug build.

Determine the dispatch type of invoke-static/-direct in a
special pass right after the type inference. This allows the
inliner to pass the "needs dex cache" check and inline more.
It also allows the code generator to avoid requesting a
register location for the ArtMethod* for kDexCachePcRelative
and direct methods.
The supported dispatch check handles also situations that
the CompilerDriver currently doesn't allow. The cleanup of
the CompilerDriver and required changes to Quick will come
in a separate change.
