cdeb6e792f Add --instr-count-dpi option, change default to 200 
This replaces the former static AstNode::INSTR_COUNT_DPI, and makes it
user adjustable to fit the design.

Fixes #3068.

708abe0dd1 Introduce model interface class, make $root part or Syms (#3036) 
This patch implements #3032. Verilator creates a module representing the
SystemVerilog $root scope (V3LinkLevel::wrapTop). Until now, this was
called the "TOP" module, which also acted as the user instantiated model
class. Syms used to hold a pointer to this root module, but hold
instances of any submodule. This patch renames this root scope module
from "TOP" to "$root", and introduces a separate model class which is
now an interface class. As the root module is no longer the user
interface class, it can now be made an instance of Syms, just like any
other submodule. This allows absolute references into the root module to
avoid an additional pointer indirection resulting in a potential speedup
(about 1.5% on OpenTitan). The model class now also contains all non
design specific generated code (e.g.: eval loops, trace config, etc),
which additionally simplifies Verilator internals.

Please see the updated documentation for the model interface changes.

Implement a distinct constant pool (#3013) 
What previously used to be per module static constants created in
V3Table and V3Prelim are now merged globally within the whole model and
emitted as part of a separate constant pool. Members of the constant
pool are global variables which are declared lazily when used (similar to
loose methods).

Emit model implementation as loose methods. (#3006) 
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.

Add ccache-report target to standard Makefile (#3011) 
Using the standard model Makefile, when in addition to an explicit
target, the target 'ccache-report' is also given, a summary of ccache
hits/misses during this invocation of 'make' will be prited at the end
of the build.

Generate SELRANGE instead of errors for potentially unreachable code (#2625) (#2754)

Fix iteration over mutating list bug in VPI impl (#2588) 
Previously, in any given VPI callback, if the callback body registered
