CogVM source as per VMMaker.oscog-eem.3470

Implement SmalltalkImage>>maxIdentityHash efficiently in the Cogit.
It's used a lot (e.g. in Dictionary lookup).

Eliminate warnings in computing jump spans on x86_64.

Slang:
Eliminate statements following a return inserted into a block in
optimization up to the next label.  Get printing semicolons after
the last label in a block correct.  Eliminate a spurious cr in
comments marking the end of inlinings.  Further adapt to
Compiler-eem.508. Don't suppress output of comments for
TLabeledCommentNode when sent from TStmtListNode gen loop.
