Modernize va args (#2214) 
Verilator uses a form of variadic macros that are nonstandard, making it
unable to be compiled under MSVC.  Replace the old synax with the
standard syntax.  This fixes MSVC usage.

Allow assert disable (#2168) 
* Add +verilator+noassert flag

This allows to disable the assert check per simulation argument.

* Add AssertOn check for assert

Insert the check AssertOn to allow disabling of asserts.
Asserts can be disabled by not using the `--assert` flag or by calling
`AssertOn(false)`, or passing the "+verilator+noassert" runtime flag.
Add tests for this behavior.
Bad tests check that the assert still causes a stop.
Non bad tests check that asserts are properly disabled and cause no stop
of the simulation.

Fixes #2162.

* Add description for single test execution

Without this description it is not obvious how to run a single test from
the regression test suite.

Geza Lore 220daa5f33 Internals: Restore AstNode naming property. #2133. 
The intention was that all subclasses of AstNode which are
intermediate must be abstract as well and called AstNode*. This was
violated recently by 28b9db1903. This
patch restores that property by:
- Renaming AstFile to AstNodeFile
- Introducing AstNodeSimpleText as the common base of AstText and
  AstTextBlock, rather than AstTextBlock deriving from AstText.
