[analyzer] Don't inline constructors for objects allocated with operator new.

[analyzer] Don't inline constructors for objects allocated with operator new.

Because the CXXNewExpr appears after the CXXConstructExpr in the CFG, we don't
actually have the correct region to construct into at the time we decide
whether or not to inline. The long-term fix (discussed in PR12014) might be to
introduce a new CFG node (CFGAllocator) that appears before the constructor.

Tracking the short-term fix in <rdar://problem/12180598>.
