-fpack-struct's handling has changed in CC1 (one of only two flags that needed changing) because the driver treats "-fpack-struct" as a boolean flag, and CC1 (did) treat it as an option with a separated value.

This change causes -fpack-struct=X to be forwarded correctly to -fpack-struct=X instead of erroneously to "-fpack-struct X"

Note that support for rvalue references does not imply support
for the full set of move-related STL operations.

I've preserved support for an odd little thing in insert() where
we're trying to support inserting a new element from an existing
one.  If we actually want to support that, there's a lot more we
need to do:  insert can call either grow or push_back, neither of
which is safe against this particular use pattern.

Refine analyzer diagnostics by adding an expression "cone-of-influence" to reverse track interesting
values through interesting expressions.  This allows us to map from interesting values in a caller
to interesting values in a caller, thus recovering some precision in diagnostics lost from IPA.

declared in a subclass has consistent parameter types with a method
having the same selector in a superclass performs a significant number
of lookups into the class hierarchy. In the example in
<rdar://problem/11004361>, we spend 4.7% of -fsyntax-only time in
these lookups.

Optimize away most of the calls to this routine
(Sema::CompareMethodParamsInBaseAndSuper) by first checking whether we
have ever seen *any* method with that selector (using the global
selector table). Since most selectors are unique, we can avoid the
cost of this name lookup in many cases, for a 3.3% speedup.

reason about the expression.

This essentially keeps more history about how symbolic values were
constructed. As an optimization, previous to this commit, we only kept
the history if one of the symbols was tainted, but it's valuable keep
the history around for other purposes as well: it allows us to avoid
constructing conjured symbols.

Specifically, we need to identify the value of ptr as
ElementRegion (result of pointer arithmetic) in the following code.
However, before this commit '(2-x)' evaluated to Unknown value, and as
the result, 'p + (2-x)' evaluated to Unknown value as well.

int *p = malloc(sizeof(int));
ptr = p + (2-x);
