Don't clear satisfaction cache for an automatic constant.

Improve C++ fold caching efficiency.

While looking at concepts caching I noticed that we were clearing the caches
unnecessarily for non-constant initialization, which shouldn't affect
folding.

 * typeck2.c (store_init_value): Only clear_cv_and_fold_caches if the
 value is constant.

Combine parsing_constraint_expression and satisfying_constraint_p.

The one was being used for constraint parsing and the latter for constraint
substitution, for which we want similar semantics. I also moved
processing_constraint_expression into scope_chain so that it's handled
properly by push_to_top_level. Note the FIXME I added in accessible_p.
