* Tests:Add some more signals to t_const_opt_red.v
* Optimize bit op trees such as ~a[2] & a[1] & ~a[0] to 3'b010 == (3'111 & a)
* Update src/V3Const.cpp

* Apply clang-format
* Don't edit and-or tree.
* Call matchBitOpTree() after V3Expand does its job.
* Internals: Rename newNodep -> newp. No functional change is intended.
* Internals: Remove m_sels. No functional change is intended.
* Internals: Remove stringstream. No functional change is intended.
* Internals: Use V3Number::bitIs1(). No functional change is intended.
* Internals: Use V3Number instead of std::map. Resolved laek. Result should be same.
* Internals: Resolve overload of setPolarity. No functional change is intended.
* Internals: Pass failure reason. No functional change is intended.
* Internals: Add VNUser::toPtr(). No functional change is intended.
* Internals: Use user4 instead of std::map. No functional change is intended.
* Catch up with the AST style aftre V3Expand
* Internals: Rename Context to VarInfo. No functional change is intended.
* Add some more test case
* tests:Add stats to tests
Update stats in t_merge_cond.pl as matchBitopTree does some of them.
* insert CCast if necessary
* small optimization to remove redundant bit mask
* No quick exit even when unoptimizable node is found.
* Simplify removing redundant And
* simplify
* Revert "Internals: Add VNUser::toPtr(). No functional change is intended."
This reverts commit f98dce10db.
* Consider AstWordSel and cleanup
* Update test
* Update src/V3Const.cpp
