and does the Sema on their body after the entire 
class/category @implementation is seen. This change allows messaging 
of forward private methods, as well as, access to 
synthesized ivars of properties with foward synthesize
declarations; among others. In effect, this patch removes
several restrictions placed on objective-c due to in-place
semantics processing of methods.

This was intended to land with the main work of instantiation ->
expansion, but despite running it by Doug over a month ago, I forgot to
commit it. Very sorry for that...

of the function in question when applicable (that is, not for blocks).
Patch by Joerg Sonnenberger with some stylistic tweaks by me.

When discussing this weth Joerg, streaming the decl directly into the
diagnostic didn't work because we have a pointer-to-const, and the
overload doesn't accept such. In order to make my style tweaks to the
patch, I first changed the overload to accept a pointer-to-const, and
then changed the diagnostic printing layer to also use
a pointer-to-const, cleaning up a gross line of code along the way.

Change err_pp_file_not_found back to an Error; when it's a Warning, we suppress it in system headers.  And it is not a good idea to suppress it in system headers.  (This was originally changed in r134996 to implement -MG.)

Fixes <rdar://10041960>.  And also brings down the number of warnings without a flag by one :)

This makes the code duplication of implicit special member handling even worse,
but the cleanup will have to come later. For now, this works.
Follow-up with tests for explicit defaulting and enabling the __has_feature

Doing this happens to disrupt the pattern that ARC was looking for
for move optimizations, so we need to fix that simultaneously.

Thread safety: added basic handling for pt_guarded_by/var and guarded_by/var annotations. We identify situations where we are accessing (reading or writing) guarded variables, and report an error if the appropriate locks are not held.
