The patch below (which is the one posted on bugzilla) disables
reduction handling if subscript is true, so that the reductions are

I have finally convinced myself that it is always right, as if there
is a reduction in a subscript, gfc_add_loop_ss_code will call
gfc_conv_expr_descriptor which will create a temporary, and the
reduction will be handled separatedly in a new loop initializing the
temporary.
Regression tested on x86_64-unknown-freebsd9.0.
OK for trunk/4.7?
OK. Thanks for the patch. (I believe the patch is correct; I am not 100%
sure that it is as the scalarizer tends to confuse me.)
