The patch adds support for executing scripts in the VM. When a VM script frame
is pushed, the VM steals the variables it needs from parent stacks, and puts a
reference type value in its place. When exiting the script frame, the value is
restored.

* libinterp/corefcn/call-stack.cc: push() script frame
* libinterp/corefcn/call-stack.h: New overload for push()
* libinterp/corefcn/compile.cc: Accept scripts compiling
* libinterp/corefcn/stack-frame.cc: Follow 'refs', assoc frames
* libinterp/corefcn/stack-frame.h: New functions, signatures
* libinterp/octave-value/ov-ref.cc: New ref class 'octave_value_ref_vmlocal'
* libinterp/octave-value/ov-ref.h:
* libinterp/octave-value/ov-usr-fcn.cc: Move functionality to parent class
                                        for scripts and functions.
                                        Auto-compile scripts.
* libinterp/octave-value/ov-usr-fcn.h:
* libinterp/octave-value/ov.h: Make ov and scope_stack_frame friends to call
                               is_ref().
* libinterp/parse-tree/pt-bytecode-vm.cc: New opcodes for entering and
                                          exiting scripts.
* libinterp/parse-tree/pt-bytecode-walk.cc: Compile scripts
* libinterp/parse-tree/pt-bytecode-walk.h:
* libinterp/parse-tree/pt-bytecode.h: New opcodes
* libinterp/parse-tree/pt-eval.cc: Execute scripts in VM, push frames
* libinterp/parse-tree/pt-eval.h:

Updated tests for scripts:
  * test/compile/bytecode_scripts.m: Added
  * test/compile/script1.m: Added
  * test/compile/script11.m: Added
  * test/compile/script2.m: Added
  * test/compile/script3.m: Added
  * test/compile/bytecode.tst: Updated
  * test/compile/module.mk: Include new files
