Detailed Description
An unstructured model for passing input parameters to a function.
This is the register model, meaning a collection of registers, any of which can be used to pass a parameter. This is nearly identical to ParamListStandard, but rules banning holes are not enforced, any subset of the resource list can be used. This makes sense for executables where parameters follow no conventions or only loose conventions. The assignMap() method may make less sense in this scenario.

Given an unordered list of storage locations, calculate a function prototype.
A list of input (or output) trials is given, which may have holes, invalid inputs etc. Decide on the formal ordered parameter list. Trials within the ParamActive are added, removed, or reordered as needed.
- Parameters
-
active is the given list of trials
Reimplemented from ghidra::ParamListStandard.
