Fix primitive table lexical analysis.

Sequences of digits in the table of a primitive may be matched
as decimal numbers instead of digits, and this breaks some

Implement const properties of classes.
...
This implementation works by detecting assignments
to constant properties in elaboration. Allow initializer
assignments to assign to the constant, error all other
assignments, and otherwise treat the constant like any
other property.

Implement class constructors.
...
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.
