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 iteration over mutating list bug in VPI impl (#2588) 
Previously, in any given VPI callback, if the callback body registered
the same callback, that registering would be processed in the currently
executing call to the call*Cbs function. In the worse case, this could
lead to an infinite loop.

Modernize va args (#2214) 
Verilator uses a form of variadic macros that are nonstandard, making it

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.

7ab2bdb6bb Support libgoogle-perftools-dev's libtcmalloc if available. #2137. 
As Verilator continuously allocates and releases small objects (e.g.:
AstNode, V3GraphVertex, V3GraphEdge), it spends a significant amount of
time in malloc/free and friends. This patch adds the --enable-tcmalloc
configure option to link Verilator against the high performance malloc
implementation library libtcmalloc. The default is to use libtcmalloc if
available on the system. Note that there are no source code change, we
are simply replacing the standard library memory allocation functions.

Measured major compilation speed improvement of 27% when running
Verilator with -O3 on a large design.

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.

d6ac351dcb Add --public-flat-rw switch, bug1511. 
This switch exposes VARs, PORTs and WIREs to C++ code. It must be use
with care as it has a significant performance impact and may result in
mis-simulation of generated clocks. Anyhow, it is prefered over
--public and useful for VPI.
