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.

c67fe02f06 Do not generate debug info in tests 
Pointless and takes up a lot of cache space in CI, so remove -ggdb and
associated debug options from tests.

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.

Fix --protect-ids when using SV classes (#2994) 
A few names were incorrectly mangled, which made --protect-ids produce
invalid output when certain SV class constructs were uses. Now fixed and
added a few extra tests to catch this.

Improve Reloop to accept constant index offsets. (#2939) 
V3Reloop now can roll up indexed assignments between arrays if there is a

a[0] = b[2];
a[1] = b[3];
...
a[x] = b[x + 2];

Stop checking dtype for better optimization chance in BitOpTree (#2909) 
* Tests: Add more case that does not match native C++ width (8, 16, 32 or 64).

* Use AstVarRef::same() instead of AstNode::sameGateTree() because the latter checks dtype in addition to scope.

AstVarRef may have different minWidth in some cases,
but the difference should be ignored in the context of bitOpTree optimization.

Allow overlaps in priority case statements (#2864) 
This will still warn if a case item is completely covered by previous
items, but will no longer complain about overlaps like this:

    priority casez (foo_i)
      2'b ?1: bar_o = 3'd0;
      2'b 1?: bar_o = 3'd1;

Before, there was a warning for the second statement because the first
two patterns match 2'b11.

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 hierarchical verilation with explicit setting of default parameter value (#2738) 
* Test hierarchical block that is explicitly set its default parameter value.

Parameterized hierarchical block must have mangled name even when all parameters have default value,
otherwise the parameterized module will be hidden by protect-lib wrapper.

* rename variable names. No functional change is intended.

Fix VPI callback list iteration (#2644) 
The end iterator always points to an element past the end of the list.
When new elements are added to the back of the list, they are inserted
before the end iterator.
Instead, track the last element in the list at the start of processing
and stop after it's been processed.
