More cost effective and reliable island joining algorithm.
...
Rather then join islands while branches are initially created, save the
island creating for the end. This way, the process is actually recursive
and greedy, reliably collecting branches into islands without conflict.

Clear up some poor pointer management.
...
The expression for a paramter value was not well managed, given that
the eval_expr() function replaces pointers. Clear things up a bit.

Skip value range processing for parameters with no value ranges.
...
Classing parameter declarations do not need value range processing,
and in fact it can get in the way.

Add support for explicit parameter types, including real.
...
Before this, the types of parameters were always logic, only the
width and signed-ness could be controlled. A parameter may take
on implicit real values if the expression were real.
With this patch, the type for the parameter can be explicitly set
to logic or real. This also means that the parameter real valued
expressions need to be more crefully treated, possibly with casting
integral expressions to real values, or real expressions to integral
values.

Basic test of the range for logic/bool parameters.

If there is a value range for a logic/bool parameter, then test the
configured value with the range and report an error if the range is
out of bounds.

to them unless the type is explicitly expressed where the parameter
is declared.

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.
