- adds ability for substitution guards to have a constructor that has Architecture as an argument
- added extra flags enum to AMD64 to drive code emission features (currently contains UseCountLeadingZerosInstruction and UseCountTrailingZerosInstruction)
- moved lzcnt/tzcnt nodes and substitutions to com.oracle.graal.replacements.amd64
