This replaces a long list of declarations for visitor functions with
a list generated from DeclNodes.inc. Nothing really interesting came
out of it; we had comprehensive coverage anyway
(excluding FriendTemplateDecls).

passing arguments in the fixed style.
We have an abstraction for deciding this, but it's (1) deep in
IR-generation, (2) necessarily tied to exact argument lists, and
(3) triggered by unprototyped function types, which we can't
legitimately make in C++ mode. So this solution, wherein Sema
rewrites the function type to an exact prototype but leaves the
variadic bit enabled so as to request x86-64-like platforms to
pass the extra variadic info, is very much a hack, but it's one
that works in practice on the platforms that LLDB will support
in the medium term --- the only place we know of where it's a
problem is instance methods in Windows, where variadic functions
are implicitly cdecl. We may have a more abstracted base on which
to build a solution by then.

This reverts commit r184817. The failure Chandler was seeing was most likely the
bug that Bob Wilson fixed in r184870 (which was a bug caught by these tests).
To be safe, I just checked again on x86-64 mac os x/linux that this test passed
(which it did).

r177473 made us correctly consider only those declarations in the
enclosing namespace scope when looking for a friend declaration. Under
ms-extensions mode, where we do some level of friend injection, this
meant that we were introducing a new tag type into a different scope
than what Microsoft actually does. Address this by only doing the
friend injection when we didn't see any tag with that name in any
outer scope. Fixes <rdar://problem/14250378>.

* Use a single stat to find out if the file exists and if it is a regular file.
* Use early returns when possible.
* Add comments explaining why we have each check.

Armed with a much better understanding of what
TemplateSpecializationTypeLoc::initializeArgLocs actually does, I now
understand that it's fine to just use an empty TemplateArgumentLocInfo
for Integral, Declaration, and NullPtr TemplateArguments.
Fixes PR14281. (The testcases are actually derived from libcxx_test in
deduction-crash.cpp because the original testcase was impossible to reduce.)

side-effect is not sequenced before its value computation. Also fix a
mishandling of ?: expressions where the condition is constant that was
exposed by the tests for this.

They are mostly duplicated and got out of sync during the PathV1 removal. We
should factor the code somewhere, but for now a FIXME will do.

The old implementation of ms_struct in RecordLayoutBuilder was a
complete mess: it depended on complicated conditionals which didn't
really reflect the underlying logic, and placed a burden on users of
the resulting RecordLayout. This commit rips out almost all of the
old code, and replaces it with simple checks in
RecordLayoutBuilder::LayoutBitField.
This commit also fixes <rdar://problem/14252115>, a bug where class
inheritance would cause us to lay out bitfields incorrectly.

This allows clang to parse the type_traits header in Visual Studio 2012,
which is included widely in practice.
This is a rework of r163022 by João Matos. The original patch broke
preprocessing of gtest headers, which this patch addresses.
Patch by Will Wilson!
