Refactor WrapperTypeInfo.traceWrappers to WrapperTypeInfo.getHeader

Refactor WrapperTypeInfo.traceWrappers to WrapperTypeInfo.getHeader

This cl replaces traceWrappers method with getHeader. The motivation for the
original traceWrappers method was only to get HeapObjectHeader anyway, and this
refactoring simplifies current code and makes further enhancements (such as
incremental tracing :) easier.
