Move Assemblers to the Arena.
And clean up some APIs to return std::unique_ptr<> instead
of raw pointers that don't communicate ownership.

ART: Arm32 packed-switch jump tables
Add jump table support to the thumb2 assembler. Jump tables are
a collection of labels for the case targets, and an anchor label
denoting the position of the jump.
Use the jump table support to implement packed-switch support for
arm32.
Add tests for BindTrackedLabel and JumpTable to the thumb2 assembler
test.

ART: Add 16-bit Thumb2 ROR, NEGS and CMP for high registers.
Also clean up the usage of set_cc flag. Define a SetCc
enumeration that specifies whether to set or keep condition
codes or whether we don't care and a 16-bit instruction
should be selected if one exists.
This reduces the size of Nexus 5 boot.oat by 44KiB (when
compiled with Optimizing which is not the default yet).

ART: Clean up arm64 kNumberOfXRegisters usage.
Avoid undefined behavior for arm64 stemming from 1u << 32 in
loops with upper bound kNumberOfXRegisters.
Create iterators for enumerating bits in an integer either
from high to low or from low to high and use them for
<arch>Context::FillCalleeSaves() on all architectures.
Refactor runtime/utils.{h,cc} by moving all bit-fiddling
functions to runtime/base/bit_utils.{h,cc} (together with
the new bit iterators) and all time-related functions to
runtime/base/time_utils.{h,cc}. Improve test coverage and

Opt compiler: Speedup div/rem by constants on arm32 and arm64.
This patch also includes:
1. Add java test for div/rem negative constants.
2. Fix a thumb2 encoding issue where the last operand is
"reg, shift #amount" in some instructions.
3. Support a simple filter in arm32 assembler test to filter out
unsupported cases, such as "smull r0, r0, r1, r2".
4. Add smull arm32 assembler test.
5. Add smull/umull thumb2 test.
6. Add test for the thumb2 encoding issue which is fixed in this
patch.

Thumb2 assembler for JNI compiler and optimizing compiler
This provides a programmatic assembler for the thumb2 instruction set for
ARM. The interface is the same as the ARM assembler and the ARM assembler has
been moved into Arm32Assembler. The assembler handles most 16 and 32 bit instructions
and also allows relocations due to branch expansion. It will also rewrite cbz/cbnz
instructions if they go out of range.
It also changes the JNI compiler to use the thumb2 assembler as opposed
to forcing it to use ARM32. The trampoline compiler still uses ARM due to the
way it returns the address of its generated code. A trampoline in thumb2 is the
same size as that in ARM anyway (8 bytes).
Provides gtest for testing the thumb2 instruction output. This gtest only runs
on the host as it uses arm-eabi-objdump to disassemble the generated code. On the
target the output is not checked but the assembler will still be run to perform
all its checks.
