Subject: Implement long negate instruction in the optimizing compiler.

- 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.
