[PATCH, committed] PR middle-end/35736 -- make PREDICT_EXPR have void type

[Michael Meissner]

I committed the following patch to fix PR 35736 after doing a full bootstrap
and make check-gcc without regressions.  It looks like PREDICT_EXPR was the
only tree type created without a valid type node.

	* predict.c (build_predict_expr): Use void_type_node for the tree
	type, instead of NULL_TREE.
