fix rem_usage()
rem_usage() is used to remove an element from a def-use chain. Optionally,
if the chain become empty, the defining instruction can also be killed.
This optional part is currently be done on all pseudos but only those
having a definition should be concerned.
Fix this by adding a check so that only PSEUDO_REGs and PSEUDO_PHIs are killed.
