[PATCH]: Make lambda-code use ssa iterators

[Daniel Berlin]

This is another in a series of small, simple, cleanup patches for 
lamba-code.c

The others are unreviewed, and at
http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02711.html
and
http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02943.html

This patch simply converts a walk through STMT_USE_OPS to use the 
FOR_EACH_SSA_USE_OPERAND iterator, and calls propagate_value
instead of SET_USE to do replacement.

Bootstrapped and regtested i686-pc-linux-gnu.
Okay for mainline?

2004-10-06  Daniel Berlin  <dberlin@dberlin.org>

 	* lambda-code.c (lambda_loopnest_to_gcc_loopnest): Convert
 	to use FOR_EACH_SSA_USE_OPERAND iterator, and propagate_value.
