Patch from David Waite:
Large arrays are now created by copying in the data from smaller arrays using
System.arraycopy(). This eliminates the debug data associated with explicit
initialization statements. It is also much easier on the java compiler which
can run out of memory compiling very large machines. The downside is that it
takes slightly longer to initialize static data.

The p varialbe is now set up at the beginning of a scanner action, rather than
at the end. This leaves scanner actions free to manipulate p and removes the
need for the special holdTE and execTE (TE for tokend) versions of hold and
exec. It also removes the need to set p = tokend-1 immediately before any
control flow.
The error handler in LmSwitch actions is now generated by the frontend, rather
than the backend. This became possible when the creation of the error state was
moved to the frontend.
