In InstructionWithAbsorbingInputSimplifier there is code optimizing a%1
and a%-1. So the code in InstructionCodeGeneratorARM64 optimizing such
cases can be deleted.
This patch deletes the code from InstructionCodeGeneratorARM64 and adds
additional tests.
Test: 012-math, 014-math3, 411-optimizing-arith, 411-checker-hdiv-hrem-pow2
Test: 701-easy-div-rem, 442-checker-constant-folding
Test: test-art-host, test-art-target

And remove obsolete "doThrow" statements.
Test: testrunner.py --host -t 411-optimizing-arith

- Add support for the neg-long (long integer two's
complement negate) instruction in the optimizing compiler.
- Add a 64-bit NEG instruction (negq) to the x86-64
assembler.
- Generate ARM, x86 and x86-64 code for integer HNeg nodes.
- Put neg-related tests into test/415-optimizing-arith-neg.

- Emit an RSB instruction for HNeg nodes in the ARM code
generator instead of RSBS, as we do not need to update the
condition code flags in this case.
- Simply punt when trying to statically evaluate a long
unary operation, instead of aborting.
- Move a test case to the right place.

- Add support for the neg-int (integer two's complement
negate) instruction in the optimizing compiler.
- Add a HNeg node type for control-flow graphs and an
intermediate HUnaryOperation base class.
- Generate ARM, x86 and x86-64 code for integer HNeg nodes.

This also fixes an issue where we could allocate a pair register even if
one of its parts was already blocked.
