[PATCH] [4/n] Fix minor SSA_NAME leaks

[Jeff Law]

Another, this time in tree-ssa-loop-im.  In this case it's just a 
missing release_defs for a statement we know won't have virtual operands.

As with the others, I've got a reduced testcase and will be trying to 
figure out how to best utilize it.

Bootstrapped & regression tested on x86_64-linux-gnu.  Installed on the 
trunk.
