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.

The "bool" return type of Array::ThrowArrayIndexOutOfBoundsException and
Array::ThrowArrayStoreException is useless. Make them void.
Note on ARM, this removes a "cmp" instruction in AGET/APUT instructions.

Greater use of directories and namespaces.
Fix bugs that cause verify options to fail.
Address numerous other issues:
GC barrier wait occurring holding locks:
GC barrier waits occur when we wait for threads to run the check point function
on themselves. This is happening with the heap bitmap and mutator lock held
meaning that a thread that tries to take either lock exclusively will block
waiting on a thread that is waiting. If this thread is the thread we're waiting
to run the check point then the VM will deadlock.
This deadlock occurred unnoticed as the call to check for wait safety was
removed in: https://googleplex-android-review.googlesource.com/#/c/249423/1.
NewTimingLogger:
Existing timing log states when a split ends but not when it begins. This isn't
good for systrace, in the context of GC it means that races between mutators
and the GC are hard to discover what phase the GC is in, we know what phase it
just finished and derive but that's not ideal.
Support for only 1 discontinuous space:
Code special cases continuous and large object space, rather than assuming we
can have a collection of both.
Sorted atomic stacks:
Used to improve verification performance. Simplify their use and add extra
checks.
Simplify mod-union table abstractions.
Reduce use of std::strings and their associated overhead in hot code.
Make time units of fields explicit.
Reduce confusion that IsAllocSpace is really IsDlMallocSpace.
Make GetTotalMemory (exposed via System) equal to the footprint (as in Dalvik)
rather than the max memory footprint.

Make the instrumentation responsible for whether we want method entry/exit
stubs, and allow it to use interpreter entry stubs when instruction by
instruction instrumentation is required. Improve deoptimization so more JDWP
test cases are passing.
Refactor exception debug posting, in particular improve reporting in the
interpreter. Improve class linker exception throwing so that broken dex files
are more likely to be reported. Fixes the performance issue Bug: 8410519.
Fix some error reporting lock level errors for the large object space. Make
fast object verification faster.
Add some debug mode robustness to finding dex PCs in GC maps.
Add printf attributes to JniAbortF and fix errors.
Expand run-test 044 to test return behaviors and fix issues with not throwing
appropriate exceptions for proxies.
Ensure causes are reported with a class linker NoClassDefFoundError and JNI
NoSuchFieldError.
Remove unused debugMe and updateDebuggerFromCode.
There's a minor sizing tweak to the arg array builder, and an extra reference
array check in the interpreter.
Some clean-up of trace code.
Fix reg type cache destructor if it is called after the reg type cache is
shutdown (as is the case in oatdump).

Performance had regressed due to verify object and method invocation changes.
Avoid trampolines for static calls in same class.
Various inlining changes.
Make verify object something that's only compiled-in in debug builds.

Break object.h into constituent files.
Reduce number of #includes in other GC header files.
Introduce -inl.h files to avoid mirror files #include-ing each other.
Check invariants of verifier RegTypes for all constructors.
