Clean up OatQuickMethodHeader after Quick removal.
This reduces the size of the pre-header by 8 bytes, reducing
oat file size and mmapped .text section size. The memory
needed to store a CompiledMethod by dex2oat is also reduced,
for 32-bit dex2oat by 8B and for 64-bit dex2oat by 16B. The
aosp_flounder-userdebug 32-bit and 64-bit boot.oat are each
about 1.1MiB smaller.
Disable the broken StubTest.IMT, b/27991555 .

Optimizing: Clean up after const-string sharpening.
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.

Optimizing: Improve const-string code generation.
For strings in the boot image, use either direct pointers
or pc-relative addresses. For other strings, use PC-relative
access to the dex cache arrays for AOT and direct address of
the string's dex cache slot for JIT.
For aosp_flounder-userdebug:
- 32-bit boot.oat: -692KiB (-0.9%)
- 64-bit boot.oat: -948KiB (-1.1%)
- 32-bit dalvik cache total: -900KiB (-0.9%)
- 64-bit dalvik cache total: -3672KiB (-1.5%)
(contains more files than the 32-bit dalvik cache)
For aosp_flounder-userdebug forced to compile PIC:
- 32-bit boot.oat: -380KiB (-0.5%)
- 64-bit boot.oat: -928KiB (-1.0%)
- 32-bit dalvik cache total: -468KiB (-0.4%)
- 64-bit dalvik cache total: -1928KiB (-0.8%)
(contains more files than the 32-bit dalvik cache)

ART: Allow method references across oat files for multi-image, 2nd attempt.
These were disabled because we didn't have sufficient
information about the multi-image layout when processing
link-time patches in OatWriter. This CL refactors the
ELF file creation so that the information is available.
Also clean up ImageWriter to use oat file indexes instead
of filenames and avoid reopening the oat file to retrieve
the checksum.

Perform profile file analysis in dex2oat
Dex2oat can accept now multiple profile files to drive a profile based
compilation. --profile-file and --reference-profile-file speficy a pair
of profile files which will be evaluated for significant differences
before starting the compilation. If the difference is insignificant
(according to some internal metric) the compilation is skipped and a
message is logged.
Multiple pairs of --profile-file and --reference-profile-file can be
specified. This effectively enables multi user support since profiles
for different users will be kept separately.
--reference-profile-file can be left out, case in which the decision is
solely based on --profile-file. If both flags are present, then their
repetition should form unique pairs.
If the compilation is performed and --reference-profile-file is given
then its data is merged with the data from the corresponding --profile-
file and saved back to the file.
If no profile flags are given, dex2oat proceeds as before and compiles
the dex files unconditionally.
As part of this change
- merge ProfileCompilationInfo and OfflineProfilingInfo under the same
object. There was no use to keep them separate anymore.
- SaveProfilingInfo now merges the data with what was in
the file before instead of overwriting it.

Dex2oat support for multiple oat file and image file outputs.
Multiple changes to dex2oat and the runtime to support a --multi-image
option. This generates a separate oat file and image file output for
each dex file input.

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).

Remove ArtCode.
- Instead use OatQuickMethodHeader.
- Various cleanups now that we don't have all those
ArtMethod -> ArtCode -> OatQuickMethodHeader indirections.
As a consequence of this cleanup, exception handling got a bit
faster.
