Getting rid of some hard-coded strings. No functional changes intended, though some test cases needed to be updated for attribute names becoming quoted.

The MSP430Interrupt attribute does have a sema handler (it's in TargetAttributesSema). Added a FIXME about the attribute being nameless when it really does have a valid name, and a comment explaining why we're using the name instead of the attribute kind.

Fix for PR18052 - Lambdas within NSDMI's and default arguments in Nested classes.

Clang currently croaks on the following:
  struct X1 {
    struct X2 {
      int L = ([] (int i) { return i; })(2);
    };
  };

asserting that the containing lexical context of the lambda is not Sema's cur context, when pushing the lambda's decl context on.

This occurs because (prior to this patch) getContainingDC always returns the non-nested class for functions at class scope (even for inline member functions of nested classes (to account for delayed parsing of their bodies)).  The patch addresses this by having getContainingDC always return the lexical DC for a lambda's call operator.
