Performance degredation in IA32 assembler

    Details

      Description

      r13833 introduced enumerations into the IA32 assembler, resulting in more maintainable code but a 8-10% slowdown in baseline compilation rate.

      See http://jira.codehaus.org/browse/RVM-322 for performance data.

      We need to get this performance back as baseline compile time can be a significant factor in startup performance of the VM on large programs. It is also a chance to discover opportunities for improving the performance of code that is using enumerations in a controlled setting that may lead to optimizations that are more generally applicable.
