Adding statistics for comparing compiled cog methods' code size and metadata size

[kumom]

Changes:

1. Added statTotalHeaderSize, statTotalCodeSize, statTotalMapSize to Cogit
2. Added three VM parameters in to obtain these three statistics primitiveGetVMParameter:
3. Moved primitiveGetVMParameter: from class StackInterpreterPrimitives to CoInterpreterPrimitives because I wanted to access to the cogit instance.
4. Added label information in parameterLabels (which is not in the VMMaker package)
5. Changed paramsArraySize from 86 to 89 in primitiveVMParameter (the previous version should have been 87 because there has been 87 parameters before this PR).

Questions:

1. Should we move parameterLabels to this repo?
2. Should we move primitiveVMParameter to CoInterpreterPrimitives as well?

This change is not directly related to the purpose of this PR, and it is only here because I was previously cleaning up some code while I was getting familiar with the codebase. This method has no senders, so it should be safe to remove it.
