	version.lisp-expr 
Log Message:
1.0.44.33: ir2tran: Correctly set up d-x closure values for tail-local-calls.

  * Tail-local-call re-uses the current frame.  It therefore needs to
use the old-fp value from the current frame in EMIT-PSETQ-MOVES.

  * "implicit" value cells need to use the /current/ frame pointer in
EMIT-PSETQ-MOVES to correctly initialize the closure.

  * Therefore: Add a new &optional argument to EMIT-PSETQ-MOVES for
the frame-pointer to be used in closure initialization.

  * This fixes the obvious part of lp#681092, but unless there is a
guarantee that the stack slots used for the "implicit" value cells
remain unused in the tail-called function then all this does is drive
the bug to become more subtle.
