34a0bb448e Improve V3MergeCond 
- Merge AstNodeIf nodes as well (not just assignment from AstCond)
- Merge merged results recursively (optimizes nested conditionals/ifs)
- Only checking mergeability once per node.
- Don't add redundant masking
- Duplicate cheap statements in both branches, if doing so yields a
  larger merge
- Include reduced nodes before the starting conditional in the merge

8681861be9 Improve bitop tree optimization 
- Remove redundant casting
- Cheaper final XOR parity flip (~/^1 instead of != 0)
- Support XOR reduction of ~XOR nodes
- Don't add redundant masking of terms
- Support unmasked terms
- Add cheaper implementation for single bit only terms
- Ensure result is clean under all circumstances (this fixes current bugs)

Fix re-evaluation of logic dependent on state set in DPI exports (#3091). 
Verilator should now correctly re-evaluate any logic that depends on
state set in a DPI exported function, including if the DPI export is
called outside eval, or if the DPI export is called from a DPI import.

Whenever the design contains a DPI exported function that sets a
non-local variable, we create a global __Vdpi_export_trigger flag, that
is set in the body of the DPI export, and make all variables set in any
DPI exported functions dependent on this flag (this ensures correct
ordering and change detection on state set in DPI exports when needed).
The DPI export trigger flag is cleared at the end of eval, which ensured
calls to DPI exports outside of eval are detected. Additionally the
ordering is modifies to assume that any call to a 'context' DPI import
might call DPI exports by adding an edge to the ordering graph from the
logic vertex containing the call to the DPI import to the DPI export
trigger variable vertex (note the standard does not allow calls to DPI
exports from DPI imports that were not imported with 'context', so we
do not enforce ordering on those).

00fe36f44c Name temporary variables based on hash of related node. 
This improves output stability by removing sequence numbers and hence
can improve ccache hit rate. No functional change intended.

Also add 'h' prefix to all printed hashes, to reduce ambiguity. No
functional change.
