Matthew Ballance 80dd984780 Fix infinite recursion in visit(AstCovergroup*) and fileline 
Two bugs in the covergroup -> AstClass transformation in V3LinkParse:

1. Infinite recursion: when a covergroup has a clocking event (e.g.
   `@(posedge clk)`), visit(AstCovergroup*) embeds a sentinel
   AstCovergroup node inside the new AstClass to carry the event for
   V3Covergroup.cpp. The subsequent iterate(cgClassp) call then visits
   the sentinel via visit(AstNodeModule*) -> iterateChildren -> which
   hits visit(AstCovergroup*) again, creating another class with another
   sentinel, infinitely.

   Fix: skip transformation in visit(AstCovergroup*) when already inside
   a covergroup class (m_modp->isCovergroup()), so sentinel nodes are
   left alone.

2. Wrong fileline column: AstCovergroup was created with the fileline of
   the identifier token ($<fl>2, the name position) rather than the
   'covergroup' keyword token ($<fl>1). This caused warnings about the
   covergroup to point to the name column instead of the keyword column.

   Fix: use $<fl>1 (the 'covergroup' keyword fileline) when constructing
   AstCovergroup in the parser.

Matthew Ballance 10b590c6ac verilog.y: fix accidental DEL omissions for wait_order, expect, property case 
Three node deletions were accidentally dropped from the initial covergroup
commit as collateral damage:
- wait_order (no-stmt variant): restore DEL($3) for vrdList
- expect (no-stmt variant): restore DEL($3) for property_spec
- property_exprCaseIf yIF/yELSE: restore DEL($3) for condition expr

In all three cases $3 is an AstNode* that is not assigned to $$ and would
be leaked without the deletion.

Matthew Ballance d9060bc9d3 Gate V3Covergroup pass on useCovergroup() flag 
Add v3Global.useCovergroup() flag (following the useRandSequence()
pattern) that is set to true when a covergroup_declaration is parsed.
Gate the V3Covergroup::covergroup() pass in Verilator.cpp on this flag
so the pass is skipped entirely for designs with no covergroups.
