using lisp value stack for call frames instead of the C stack
...
adding the ability to grow the value stack as needed
the net effect is that calls use much less space, and stack frames
can use all available heap space. the only downside is that C builtins
must be aware that the stack can change out from under them if they call
lisp code. currently the only example of this is table.foldl.
also fixing bug where exceptions failed to unwind the gc handle stack.

adding the ability for the VM to use computed goto where available
...
with gcc v4.3.2 I found the combination of -O2 and computed goto to give the
best performance; with -O3 performance was a little worse and computed goto
was a wash.
