The problem here is that the SLSR pass is promoting a POINTER_PLUS_EXPR
to a PLUS_EXPR.  Since pointer arithmetic is invalid in
{PLUS,MINUS}_EXPR's, the gimple verifier chokes on the invalid statement.
Fixed by maintaining the POINTER_PLUS_EXPR when appropriate.

OK for trunk?
The ChangeLog mentions POINTER_MINUS_EXPR, which doesn't exist.

Actually the ChangeLog is correct, what was incorrect was the svn commit message. Is there a way to change the commit message retroactively?
