Revert r56315. When the instruction to speculate is a load, this
code can incorrectly move the load across a store. This never
happens in practice today, but only because the current
heuristics accidentally preclude it.

Fixed a problem in our local Clang's method for
performing Objective-C instance variable lookup.
Previously, it only completed the derived class
that was the beginning of the search. Now, as
it walks up the superclass chain looking for the
ivar, it completes each superclass in turn.
Also added a testcase covering this issue.

Tweak the fix to PR8977: an empty expression-list represents value initialization, not default initialization. Fixes PR11712.

Don't seed the ASTWriter's declaration -> ID mapping with the IDs of
each deserialized declaration, since that information is already
available in each declaration.

When we deserialize a declaration from a module file, allocate extra
storage for the global declaration ID. Declarations that are parsed
(rather than deserialized) are unaffected, so the number of
declarations that pay this cost tends to be relatively small (since
relatively few declarations are ever deserialized).
This replaces a largish DenseMap within the AST reader. It's not
strictly a win in terms of memory use---not every declaration was
added to that DenseMap in the first place---but it's cleaner to have
this information available for every deserialized declaration, so that
future clients can rely on it.
