This patch supersedes my previous lexical scope patch 
<URL: http://rt.perl.org/rt2/Ticket/Display.html?id=15800 >

In this implementation, find_lex and store_lex only operate on the
current pad, and open_lex/close_lex have been renamed to
new_pad/pop_pad.

The implementation is still quite simple (no pad descriptors, no
accessing by index), but is at least a start on what is needed.

The files affected by the patch are:
- core.ops: added implementation the 4 ops.
- dod.c: added interpreter->ctx.pad_stack to the initial first dod pass
  (I am not sure how to test if this is correct ...)
- interpreter.c and interpreter.h: added pad_stack to Parrot_Context.

In addition to the patch an updated test and example pasm file are
attached:

- lexicals.t: simple tests for the 4 ops that should to in t/op/
- lexicals.pasm: simple example that should go in examples/assembly/

Again, comments welcome.
