Add long bitwise not instruction in the optimizing compiler.

- Add support for the not-long (long integer one's
  complement negation) instruction in the optimizing
  compiler.
- Add a 64-bit NOT instruction (notq) to the x86-64
  assembler.
- Generate ARM, x86 and x86-64 code for long HNot nodes.
- Gather not-related tests in test/416-optimizing-arith-not.
