Log:
	PR c++/92150 - partial specialization with class NTTP.

Here unify was getting confused by the VIEW_CONVERT_EXPR we add in
finish_id_expression_1 to make class NTTP const when they're used in an
expression.

Tested x86_64-pc-linux-gnu, applying to trunk.

	* pt.c (unify): Handle VIEW_CONVERT_EXPR.
