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.

* Correct file location

* Add description for single test execution

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

Stefan Wallentowitz 045ff25f80 Support vpiModule, bug1469. 
Add very basic support for vpiModule. Basically it allows to traverse
the module tree to find a variable etc. It does not support more than
vpi_iterate and vpi_scan for vpiModule along basic operations like
vpi_get_str on vpiModule.

The support is added non-intrusively to non-VPI verilator runs. It
essentially:

 - Tracks the creation of cell instances and keeps them alive until
   the emit phase. They are there converted to scopes if modules.

 - Emits empty (don't add anything during construction)
   VerilatedScopes for all inlined modules, only for those inlined
   modules that are on the hierarchical path to public variables.

 - Adds VerilatedHierarchy as abstraction to structure of the
   scopes. It is only created for VPI designs. It allows to traverse
   the hierarchy from the top (NULL).
