6b46da0240 Create /*verilator coverage_on/off*/ instead of coverage_module_off. 
This allows finer grained bracketing of sections of interest.
Convert tracing_on/off to use the same general scheme.

8b77379e2c Internal coding: Assert that user#() don't overlap. 
Any use of a user() must now be declared, generally in the Visitor class with
    AstUser#InUse   arbitrary_object
This lets the code track if there's another request for the same user(),
preventing nasty hard to debug cases where they overlap.  This will also
call user#ClearTree(), so a bunch of those were removed, though many
extranious ones still remain.

09b7ba1317 Internal rework, no functionality change. 
Rework V3EmitC to use a little template language for code to output,
similar to emitVerilog() functions.  Change all emitOperator() to
emitC(), elimate emitWordForm().
