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)

Clean up V3Combine (#2965)
- Remove dead code
- Simplify what is left
- Minor improvements using C++11
- Remove special case AstNode constructors used only in one place in
  V3Combine (inlined instead).

Make all AstNode* base class constructors protected. (#2962)
No functional changes intended. Boring patch in the hope of being
helpful to new contributors. Although AstNode* base classes needing to
be abstract is described in the internals manual, this might provide a
bit of extra safety.

Don't emit empty files with low split limits (#2961)
Attempt to split output files when we know a function will actually be
emitted, otherwise we might end up with empty files.

Internals: Make AstAlwaysPost an AstNodeProcedure. (#2959)
This seems to belong there, eliminates some code duplication in V3Clock,
and also enables splitting AstAlwaysPost statements into different
functions in V3Order, but should otherwise have little effect.

Split procedures to better respect --output-split-cfuncs (#2942)
CFuncs only used to be split at procedure (always/initial/final block),
which on occasion can still yield huge output files if they have large
procedures. This patch make CFuncs split at statement boundaries within
procedures. This has the potential to help a lot, but still does not
help if there are huge statements within procedures.

Improve Reloop to accept constant index offsets. (#2939)
V3Reloop now can roll up indexed assignments between arrays if there is a
constant offset between indices on the left and right hand sides, e.g.:

a[0] = b[2];
a[1] = b[3];
...
a[x] = b[x + 2];

Stop checking dtype for better optimization chance in BitOpTree (#2909)
* Tests: Add more case that does not match native C++ width (8, 16, 32 or 64).

* Use AstVarRef::same() instead of AstNode::sameGateTree() because the latter checks dtype in addition to scope.

AstVarRef may have different minWidth in some cases,
but the difference should be ignored in the context of bitOpTree optimization.

Allow overlaps in priority case statements (#2864)
This will still warn if a case item is completely covered by previous
items, but will no longer complain about overlaps like this:

    priority casez (foo_i)
      2'b ?1: bar_o = 3'd0;
      2'b 1?: bar_o = 3'd1;

Before, there was a warning for the second statement because the first
two patterns match 2'b11.

Generate SELRANGE instead of errors for potentially unreachable code (#2625) (#2754)
When using a "if" statement inside an always block, part of the code may
be unreachable. This can be used to avoid errors, but it generated an
error, this commit demotes this to a warning. Partly fixes #2625.

Fix hierarchical verilation with explicit setting of default parameter value (#2738)
* Test hierarchical block that is explicitly set its default parameter value.

Parameterized hierarchical block must have mangled name even when all parameters have default value,
otherwise the parameterized module will be hidden by protect-lib wrapper.

* rename variable names. No functional change is intended.
