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

Geza Lore ce03293128 Generate AstNode accessors via astgen 
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.

Geza Lore 96a4b3e5a5 Update clang-format config and apply 
- Regroup and sort #include directives (like we used to, but automatic)
- Set AlwaysBreakTemplateDeclarations to true

Geza Lore 152a6cd886 Improve AstNode::foreach (also exists and forall) 
Speed improvements:
- Use a direct, recursion-free implementation
- Improve pre-fetching

Functionality:
- Support remove/replace of currently iterated node

Geza Lore f8c0169e82 Implement 'forceable' attribute 
Using the 'forceable' directive in a configuration file, or the /*
verilator forceable */ metacomment on a variable declaration will
generate additional public signals that allow the specified signals to
be forced/released from the C++ code.

Geza Lore 539c9d4c63 Merge alternate 'force'/'release' implementation 
- Add more tests, including for tracing.
- Apply some cleaner, more generic abstractions in the implementation.
- Use clearer AstRelease which is not an assignment.
