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).

Remove c++filt and fix status code of Makefile, bug1265 In the generated Makefile the linker output is piped through c++filt which was very useful for older linkers. But unfortunately the status code is lost during the piping. So when the make process is embedded in a larger setup a failure will not manifest to the outside flow. As modern linkers do the job of c++filt, this removes it from the generated Makefile. It will also produce a proper status code then. Signed-off-by: Wilson Snyder <wsnyder@wsnyder.org>

** $finish will no longer exit, but set Verilated::gotFinish().
This enables support for final statements, and for other cleanup code.
If this is undesired, redefine the vl_user_finish routine. Top level
loops should use Verilated::gotFinish() as a exit condition for their
loop, and then call top->final(). To prevent a infinite loop, a
double $finish will still exit; this may be removed in future
releases.
*** Add support for SystemVerilog keywords $bits, $countones, $isunknown,
$onehot, $onehot0, always_comb, always_ff, always_latch, finish.

** Internal changes to support future clocking features.
** Verilog-Perl and SystemPerl are no longer required for C++ or SystemC
output. If you want tracing or coverage analysis, they are still needed.
*** Added --sc to create pure SystemC output not requiring SystemPerl.

*** The --exe flag is now required to produce executables inside the makefile.
This was previously the case any time .cpp files were passed on the
command line.
*** Added -O3 and --inline-mult for performance tuning. [Ralf Karge]
One experiment regained 5% performance, at a cost of 300% in compile time.

** Verilator now uses 64 bit math where appropriate.
Inputs and outputs of 33-64 bits wide to the C++ Verilated model must
now be uint64_t's; SystemC has not changed, they will remain sc_bv's.
This increases performance by ~ 9% on x86 machines, varying with how
frequently 33-64 bit signals occur. Signals 9-16 bits wide are now
stored as 16 bit shorts instead of longs, this aids cache packing.
**** Fixed SystemC compile error with feedthrus. [Paul Nitza]

** BETA VERSION, USE 3.124 for stable release!
** Version 3.2XX includes a all new back-end.
This includes automatic inlining, flattening of signals between
hierarchy, and complete ordering of statements. This results in
60-300% execution speedups, though less pretty C++ output. Even
better results are possible using GCC 3.2.2 (part of Redhat 9.1), as
GCC has fixed some optimization problems which Verilator exposes.
If you are using `systemc_ctor, beware pointers to submodules are now
initialized after the constructor is called for a module, to avoid
segfaults, move statements that reference subcells into initial
statements.
*** C++ Constructor that creates a verilog module may take a char* name.
This name will be used to prefix any $display %m arguments, so users may
distinguish between multiple Verilated modules in a single executable.

** Added support for functions.
*** Signals 8 bits and shorter are now stored as chars
instead of uint32_t's. This improves Dcache packing and
improves performance by ~7%.
**** $display now usually results in a single VL_PRINT rather then many.

*** --private and --l2name are now the default,

** $c can now take multiple expressions as arguments.
For example $c("foo","bar(",32+1,");") will insert "foobar(33);"
This makes it easier to pass the values of signals.
** Several changes to support future versions that may have
signal-eliminating optimizations. Users should try to use these switch
on designs, they will become the default in later versions.
*** Added --private switch and /*verilator public*/ metacomment.
This renames all signals so that compile errors will result if any
signals referenced by C++ code are missing a /*verilator public*/
metacomment.
*** With --l2name, the second level cell C++ cell is now named "v".
Previously it was named based on the name of the verilog code. This
means to get to signals, scope to "{topcell} ->v ->{mysignal}" instead
of "{topcell} ->{verilogmod}. {mysignal}". This allows different
modules to be substituted for the cell without requiring source
changes.
**** Several cleanups for Redhat 8.0.
