Log:
[ASTImporter] Implement some expression-related AST node import (part 2)
* Some code cleanup
* Add tests not present in http://reviews.llvm.org/D14286
* Integrate a test suite from Serge Pavlov (http://reviews.llvm.org/D14224)
* ArrayTypeTraitExpr: serialize sub-expression to avoid keeping it undefined
* Implement import of some nodes:
- ArrayTypeTraitExpr
- ExpressionTraitExpr
- OpaqueValueExpr
- ArraySubscriptExpr
- ExplicitCastExpr
- ImplicitValueInitExpr
- OffsetOfExpr
- CXXThisExpr
- CXXThrowExpr
- CXXNoexceptExpr
- CXXDefaultArgExpr
- CXXScalarValueInitExpr
- CXXBindTemporaryExpr
- CXXTemporaryObjectExpr
- MaterializeTemporaryExpr
- ExprWithCleanups
- StaticAssertDecl
- FriendDecl
- DecayedType
