A couple of missing "RequireNonAbstractType" calls in conditional operator
handling. I looked for opportunities to tie this check in to all relevant
callers of PerformCopyInitialization (couldn't be all callers since this is
called for base subobject copying too, where it's acceptable to copy abstract
types) but the callers varied too much & in many cases had substantial code
or conditionals on the RequireNonAbstractType call, the
PerformCopyInitialization call, or the code between the two calls.

analysis that may give false positives because it is confused by aliasing, and
a less precise analysis that has fewer false positives, but may have false
negatives. The more precise warnings are enabled by -Wthread-safety-precise.
An additional note clarify the warnings in the precise case.

contain call to 'super' if they have 'super' class and it has the method
with this attribute set. This is wip. // rdar://6386358

unexpanded parameter pack is a pack expansion. Thus, as with a non-type template
parameter which is a pack expansion, it needs to be expanded early into a fixed
list of template parameters.
Since the expanded list of template parameters is not itself a parameter pack,
it is permitted to appear before the end of the template parameter list, so also
remove that restriction (for both template template parameter pack expansions and
non-type template parameter pack expansions).

These types are defined differently on 32-bit and 64-bit platforms, and
trying to offer a fixit for one platform would only mess up the format
string for the other. The Apple-recommended solution is to cast to a type
that is known to be large enough and always use that to print the value.
This should only have an impact on compile time if the format string is
incorrect; in cases where the format string matches the definition on the
current platform, no warning will be emitted.

(__builtin_* etc.) so that it isn't possible to take their address.
Specifically, introduce a new type to represent a reference to a builtin
function, and a new cast kind to convert it to a function pointer in the
operand of a call. Fixes PR13195.

initiated enum constant has the same value as another enum constant.
For instance:
enum test { A, B, C = -1, D, E = 1 };
Clang will warn that:
A and D both have value 0
B and E both have value 1
A few exceptions are made to keep the noise down. Enum constants which are
initialized to another enum constant, or an enum constant plus or minus 1 will
not trigger this warning. Also, anonymous enums are not checked.
