ClassLinker can now FindClass all libcore classes

Summary:
- added ClassLinkerTest/LibCore test of finding all libcore classes
- fixed bug in LinkInterfaceMethods appending mirant methods to vtable_
- fixed bug in LinkVirtualMethods allocating subclass vtable_
- fixed mmap bug in MarkStack::Init
- bumped default (and max) heap sizes to handle ClassLinkerTest/LibCore
- made ObjectArray a templated class
- heap allocate Class::vtable_
- "mm test-art" and "mm test-art-target" added
- new is_host_ for use by tests

Details:

    Added support for "mm test-art" and "mm test-art-target" in addition to test-art-host
	Android.mk

    Made ObjectArray a template class for clearer declarations and to
    remove need the need for down_cast.

	src/object.h
	src/object_test.cc
	src/class_linker.cc
	src/class_linker.h
	src/dex_cache.cc
	src/dex_cache.h
	src/dex_cache_test.cc
	src/mark_sweep.cc

    Made Class::vtable_ a heap allocated ObjectArray<Method>

	src/class_linker.cc

    Fix bug in ClassLinker::LinkInterfaceMethods where we were not
    extending the vtable_ before appending miranda methods.

	src/class_linker.cc

    Changed all uses of DexFile* in ClassLinker to be const

	src/class_linker.cc
	src/class_linker.h

    Fix bug in ClassLinker::LinkVirtualMethods where we were using
    NumVirtualMethods vs vtable->GetLength when determining new max
    vtable_ length.

	src/class_linker.cc

    New ClassLinkerTest/LibCore that enumerates the libcore dex file
    and tries to FindClass every descriptor found.

	src/class_linker_test.cc

    Added if_host_ check for host only tests. In the future will use
    for picking proper location of files, etc. on host vs target.

	src/common_test.h

    Fixed test to use ClassLinker::AllocDexCache

	src/dex_cache_test.cc

    Fixed fooIds comments to foo_ids_

	src/dex_file.h

    Bumped default heap size (and max as well) to make ClassLinkerTest/LibCore run

	src/heap.h

    Fixed bug where we were not using MAP_ANONYMOUS for MarkStack
    allocation found running ClassLinkerTest/LibCore.

	src/mark_stack.cc
