RFR(S): 8077843: adlc: allow nodes that use TEMP inputs in expand rules.

[Lindenmaier, Goetz]

Hi,

I have a tiny fix that allows nodes that use TEMP inputs / TEMP effect in
expand rules.

Currently an assertion fires if you do so.
This is harmless, though, as the TEMP node is added in the Expand() of the used node,
which is called by the Expand() of the node being expanded.
Probably the assertion was meant for the node being expanded.

The change simply removed the assertion.

Please review this change.  I please need a sponsor.

I need this feature for a change I intend to do in the ppc.ad file.

Best regards,
  Goetz.
