* tree-into-ssa.c (prepare_operand_for_rename): New argument is_use.
If the operand is for a use, then strip away the SSA_NAME, do not
strip away the SSA_NAME for a set. Never call release_ssa_name.

prepare_operand_for_rename. If a VDEF_RESULT is not an SSA_NAME,
then set the VDEF_RESULT to the VDEF_OP.
(set_def_block): Strip away any SSA_NAME to get to the real
underlying variable.
