Remove the function/builtin call duality when invoking upcalls. There is no need for it other than for debug consistency checks, but we can do those in a simpler way too.
-
Functions that may optionally receive no arguments should not accept nor require empty parenthesis for compatibility with other BASIC dialects. In particular, this means that RND() is now invalid and that the correct syntax is either RND or RND(1).

Generalize index assignment for builtin upcalls
Introduce a new IndexedHashMap type that wraps HashMap and extends it to assign indexes on insertion, allowing those indexes to be retrieved later on a key basis or by extracting the list of keys in insertion order. This is more complicated than it should be just for builtin upcalls but it will be used later once I implement indexes for variables and arrays as well.
-
-
Move the "long" list of arguments in the ArrayAssignment and ArrayLoad operations into an ISpan so that, when I add a runtime index to them soon, things are less confusing.
-
Group common arguments in all Load operations under a LoadSpan to make room for other arguments later on.
-
Assign indexes to dim operations
Modify the symbols table so that it assigns indexes to variables and arrays and propagate this information to the Dim and DimArray bytecode operations. This is just the beginning of adding indexes, and the indexes are not yet consumed.

This finishes modifying the bytecode so that all operations that reference symbols carry the corresponding stack index with them.
