Put in place the ARM64 instruction simplification framework.
This commit introduces and runs the empty InstructionSimplifierArm64
pass. Further commits will introduce arm64-specific transformations in
that pass.

ART: Run GraphChecker after Builder and SsaBuilder
This patch refactors the way GraphChecker is invoked, utilizing the
same scoping mechanism as pass timing and graph visualizer. Therefore,
GraphChecker will now run not just after instances of HOptimization
but after the builders and reg alloc, too.

ART: Add -Wunused
Until the global CFLAGS are fixed, add Wunused. Fix declarations
in the optimizing compiler.

Move code around and address growable_array comment.
- Move SideEffectsAnalysis to its own file.
- Move most of gvn.h to gvn.cc.
- Don't call Resize in GrowableArray constructor, but just set num_used
directly.

Introduce a SideEffectsAnalysis class.
LICM also needs the side effects information of loops, so move
the GVN::ComputeSideEffects method into its own analysis class.

Fix a bug in GVN.
When a predecessor block was killing instructions in a set, we were
not taking into account side effects of blocks between the dominator to
this predecessor.
Implementation now intersects the copied set of the dominator with
the predecessors to take these side effects into account.

Fix a bug in the type analysis phase of optimizing.
Dex code can lead to the creation of a phi with one
float input and one integer input. Since the SSA builder trusts
the verifier, it assumes that the integer input must be converted
to float. However, when the register is not used afterwards, the
verifier hasn't ensured that. Therefore, the compiler must remove
the phi prior to doing type propagation.

Move existing optimizations to it.

Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.
Fix associated errors about unused paramenters and implict sign conversions.
For sign conversion this was largely in the area of enums, so add ostream
operators for the effected enums and fix tools/generate-operator-out.py.
Tidy arena allocation code and arena allocated data types, rather than fixing
new and delete operators.
Remove dead code.

Make ART compile with GCC -O0 again.
Tidy up InstructionSetFeatures so that it has a type hierarchy dependent on
architecture.
Add to instruction_set_test to warn when InstructionSetFeatures don't agree
with ones from system properties, AT_HWCAP and /proc/cpuinfo.
Clean-up class linker entry point logic to not return entry points but to
test whether the passed code is the particular entrypoint. This works around
image trampolines that replicate entrypoints.
