Subject: [PATCH] cleanups for reduction code (autopar pass)

Hi,

This patch cleans up the reduction code :
I removed the creation of  "reduction_initial" variable, and stored the 
(user's) initialization value
in the reduction field of the shared struct.
At the join of the threads, the loaded value is already correct. 
(I removed the stmt that joins reduction_initial to the loaded value.

    * tree-parloops.c (reduiction_info): Change documentation of 
reduction_initial field. 
    (initialize_reductions): Remove creation of reduction_initial 
variable.
    (create_loads_for_reductions): don't join reduction_initial to the 
loaded value.


Tested on autopar tescases. 
Doing a full bootstrap + regression now.

Ok to commit once passes testing?
Thanks,
Razya
