c++: Micro-optimize instantiation_dependent_expression_p
This makes instantiation_dependent_expression_p avoid calling
potential_constant_expression when processing_template_decl isn't set
(and hence when value_dependent_expression_p is definitely false).
gcc/cp/ChangeLog:
* pt.c (instantiation_dependent_expression_p): Check
processing_template_decl before calling
potential_constant_expression.
