Optimize bit op tree #2186, #2632, and #2633 (#2751)
* 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
