We have a new policy in place making links to private resources
something we try to avoid in source and test files. Normally, we'd
organically switch to the new policy rather than make a sweeping change
across a project. However, Clang is in a somewhat special circumstance
currently: recently, I've had several new contributors run into rdar
links around test code which their patch was changing the behavior of.
This turns out to be a surprisingly bad experience, especially for
newer folks, for a handful of reasons: not understanding what the link
is and feeling intimidated by it, wondering whether their changes are
actually breaking something important to a downstream in some way,
having to hunt down strangers not involved with the patch to impose on
them for help, accidental pressure from asking for potentially private
IP to be made public, etc. Because folks run into these links entirely
by chance (through fixing bugs or working on new features), there's not
really a set of problematic links to focus on -- all of the links have
basically the same potential for causing these problems. As a result,
this is an omnibus patch to remove all such links.
This was not a mechanical change; it was done by manually searching for
rdar, radar, radr, and other variants to find all the various
problematic links. From there, I tried to retain or reword the
surrounding comments so that we would lose as little context as
possible. However, because most links were just a plain link with no
supporting context, the majority of the changes are simple removals.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the fourth batch of tests being updated (there are a significant
number of other tests left to be updated).
Sema actions on ObjCDictionaryLiteral and ObjCArryLiteral are currently
done as a side-effect of Sema upon parent expressions, which incurs of
delayed typo corrections for such literals to be performed by TypoTransforms
upon the ObjCDictionaryLiteral and ObjCArryLiteral themselves instead of
its elements individually.
This is specially bad because it was not designed to act on several
elements; searching through all possible combinations of corrections for
several elements is very expensive. Additionally, when one of the
elements has no correction candidate, we still explore all options and
at the end emit no typo corrections whatsoever.
Do the proper sema actions by acting on each element alone during appropriate
literal parsing time to get proper diagonistics and decent compile time
behavior.

NSNumber, and boolean literals. This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.
My apologies for the large patch. It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.
Docs are forthcoming to document the implementation and behavior of these features.
