Richard Smith 883dbc43d9 Switch from using a DiagnosticTrap and a note for "while defining a special ... member function" context notes to registering an entry on the context stack. Also reorder the steps within defining special members to be consistent. This has a few benefits: if multiple diagnostics are produced while checking such a member, the note is now attached to the first such diagnostic rather than the last, this prepares us for persisting these diagnostics between the point at which we require the implicit instantiation of a template and the point at which that instantiation is actually performed, and this fixes some cases where we would fail to produce a full note stack leading back to user code in the case of such a diagnostic. The reordering exposed a case where we could recursively attempt to define a defaulted destructor while we're already defining one (and other such cases also appear to be possible, with or without this change), so this change also reuses the "willHaveBody" flag on function declarations to track that we're in the middle of synthesizing a body for the function and bails out if we try to define a function that we're already defining. llvm-svn: 303930		2017-05-25 22:47:05 +00:00
