[patch] tree-ssa-loop-ivopts.c: Remove a redundant call toupdate_stmt.


Attached is a patch to remove a redundant call to update_stmt.

COPY shown in the patch is a newly created statement.  As such, it
does not have a statement annotation yet.  When we insert the new
statement with bsi_insert_before, it will eventually call
update_stmt_operands, so we don't need to explicitly call update_stmt

Tested on i686-pc-linux-gnu.  OK to apply?
