* Remove Tcl_Preserve support for ContLineLoc values. It's not needed.dgp2013-08-071-17/+2
| | | This allows the clLoc field of CompileEnv struct to go away too.

| | | | | | | | | | exist only for the sake of taking great pains to make sure that pure list values remain pure list values. The value of pure list values is no longer what it once was. For a long long time now, any canonical list values have been equally good. This branch is Work In Progress eliminating the complication of the additional type value. Currently some minor botches are breaking execution tracing tests.
