This preserves the existing behavior much more closely than my previous attempt.

of CXXMethodDecls and CXXConstructorDecls, which had already gotten
out-of-sync.

may have a trivial or non-trivial copy constructor.

Add simple cost model to perfect shuffle. Currently we're doing just greedy search for cost instead of (proper) dynamic programming approach.

Use masks not nodes for vector shuffle predicates. Provide set of 'legal' masks, so legalizer won't infinite cycle
