* Makefile.tpl: Whenever a recursive target is defined, wrap
it in a special @if/@endif block, and prepare its maybe
dependency in the @if/@endif block
* configure.in: Instead of writing maybe dependencies, remove
the @if/@endif statements, and remove the @if/@endif blocks
that remain.
* Makefile.in: Regenerate.
* configure: Regenerate.

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.
