Davide Italiano ccb3738527 [Sema] Don't emit "pure virtual" warning for fully qualified calls.
-fapple-kext is an exception because calls will still go through
the vtable in that mode. Add a note to make the user aware of that.

Ulrich Weigand ef5aa29e12 Support alternate attribute spelling __enable_if__
Attribute names usually support an alternate spelling that uses double
underscores before and after the attribute name, like e.g. attribute
((__aligned__)) for attribute ((aligned)). This is necessary to allow
use of attributes in system headers without polluting the name space.

However, for attribute ((enable_if)) that alternate spelling does not
work correctly. This is because of code in Parser::ParseGNUAttributeArgs
(ParseDecl.cpp) that specifically checks for the "enable_if" spelling
without allowing the alternate spelling.

Similar code in ParseDecl.cpp uses the normalizeAttrName helper to allow
both spellings. This patch adds use of that helper for the "enable_if"
check as well, which fixes attribute ((__enable_if__)).

In the test, y1 is not reference compatible to y2 and we currently assume
the cast is ill-formed so we emit a diagnostic. Instead, in order to honour
the standard, if y1 it's not reference-compatible to y2 then it can't be
converted using a static_cast, and a reinterpret_cast should be tried instead.
Richard Smith provided the correct interpretation of the standard and
explanation about the subtle difference between "can't be cast" and "the cast
is ill-formed". The former applies in this case.

Jordan Rose 9503501dae [analyzer] When forced to fake a block type, do it correctly.
BlockDecl has a poor AST representation because it doesn't carry its type
with it. Instead, the containing BlockExpr has the full type. This almost
never matters for the analyzer, but if the block decl contains static
local variables we need to synthesize a region to put them in, and this
region will necessarily not have the right type.

Even /that/ doesn't matter, unless

(1) the block calls the function or method containing the block, and
(2) the value of the block expr is used in some interesting way.

In this case, we actually end up needing the type of the block region,
and it will be set to our synthesized type. It turns out we've been doing
a terrible job faking that type -- it wasn't a block pointer type at all.
This commit fixes that to at least guarantee a block pointer type, using
the signature written by the user if there is one.

This is not really a correct answer because the block region's type will
/still/ be wrong, but further efforts to make this right in the analyzer
would probably be silly. We should just change the AST.
