[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
