Wilson Snyder 761adf1cf0 Internals: Add cloneTreePure to prepare for side effect check.
Use cloneTreePure when what is being cloned must be side-effect free.

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

Geza Lore 65e08f4dbf Make all expressions derive from AstNodeExpr (#3721).
Apart from the representational changes below, this patch renames
AstNodeMath to AstNodeExpr, and AstCMath to AstCExpr.

Now every expression (i.e.: those AstNodes that represent a [possibly
void] value, with value being interpreted in a very general sense) has
AstNodeExpr as a super class. This necessitates the introduction of an
AstStmtExpr, which represents an expression in statement position, e.g :
'foo();' would be represented as AstStmtExpr(AstCCall(foo)). In exchange
we can get rid of isStatement() in AstNodeStmt, which now really always
represent a statement

Peak memory consumption and verilation speed are not measurably changed.

Partial step towards #3420

Geza Lore 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

the generation child node (operand) accessors. Please see the updated
internal documentation for details.

Geza Lore 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.

Implement a distinct constant pool (#3013)
What previously used to be per module static constants created in
V3Table and V3Prelim are now merged globally within the whole model and
emitted as part of a separate constant pool. Members of the constant
pool are global variables which are declared lazily when used (similar to
loose methods).

Split V3Hashed to V3Hasher and V3DupFinder (#2967)
V3Hasher is responsible for computing AstNode hashes, while V3DupFinder
can be used to find duplicate trees based on hashes. Interface of
V3DupFinder simplified somewhat. No functional change intended at this
point, but hash computation might differ in minor details, this however
should have no perceivable effect on output/runtime.

Implements (#2964)
