Wildcard index type support for associative arrays (#3501). 
Associative arrays that specify a wildcard index type may be indexed by
integral expressions of any size, with leading zeros removed
automatically.  A natural representation for such expressions is a
string, especially that the standard explicitly specifies automatic
casts from string indices to bit vectors of equivalent size.
The automatic cast part is done implicitly by the existing type system.

A simpler way to just make this work would be to convert wildcard index
type to a string type directly in the parser code, but several new AST
classes are needed to make sure illegal method calls are detected.
The verilated data structure implementation is reused, because there is
no need for differentiating the behavior on C++ side.

f8c0169e82 Implement 'forceable' attribute 
Using the 'forceable' directive in a configuration file, or the /*
verilator forceable */ metacomment on a variable declaration will
generate additional public signals that allow the specified signals to
be forced/released from the C++ code.

539c9d4c63 Merge alternate 'force'/'release' implementation 
- Add more tests, including for tracing.
- Apply some cleaner, more generic abstractions in the implementation.
- Use clearer AstRelease which is not an assignment.

9a8c878f2d Avoid repeated traversal for SC text sections in emit when not needed 
Repeatedly traversing whole modules in emit (due to file splitting)
looking for `systemc_* sections can add up to a lot of time on large
designs that have been flattened and need to be split into many files.
Assuming `systemc_* is a rarely used feature, just don't bother if we
don't need to. This gain 9% verilation speed improvement on a large
benchmark.
