3abb65d732 Strengthen AstNode types to AstNodeExpr 
Declare every AstNode children and variables as AstNodeExpr where we
statically know this is the appropriate sub-type.

63c694f65f Streamline dump control options 
- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
  special case of `--dumpi-<tag>` where tag can be a magic word, or a
  filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
  works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
  special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before

0c70a0dcbf Remove redundant 'virtual' keywords from overridden methods 
'virtual' is redundant when 'override' is present, so keep only
'override'.

Add t/t_dist_cppstyle.pl to check for this.

Wildcard index type support for associative arrays (#3501). 
Associative arrays that specify a wildcard index type may be indexed by
integral expressions of any size, with leading zeros removed
automatically.  A natural representation for such expressions is a
string, especially that the standard explicitly specifies automatic
casts from string indices to bit vectors of equivalent size.
The automatic cast part is done implicitly by the existing type system.

A simpler way to just make this work would be to convert wildcard index
type to a string type directly in the parser code, but several new AST
classes are needed to make sure illegal method calls are detected.
The verilated data structure implementation is reused, because there is
no need for differentiating the behavior on C++ side.

Generate SELRANGE instead of errors for potentially unreachable code (#2625) (#2754) 
When using a "if" statement inside an always block, part of the code may
be unreachable. This can be used to avoid errors, but it generated an
error, this commit demotes this to a warning. Partly fixes #2625.
