recursively within the emission of another inline function. This ultimately
led to us emitting the same inline function definition twice, which we then
rejected because we believed we had a mangled name conflict.

Yet more problems due to the missing CXXBindTemporaryExpr in the CFG for
default arguments.
Unfortunately we cannot just switch off inserting temporaries for the
corresponding default arguments, as that breaks existing tests
(test/SemaCXX/return-noreturn.cpp:245).

of MIPS toolchains.
The uCLibc implemented for multiple architectures. A couple of MIPS toolchains
contains both uCLibc and glibc implementation so these options allow to select
used C library.
Initially -muclibc / -mglibc (as well as -mbionic) have been implemented in gcc
for various architectures so they are not MIPS specific.

With modules we start accessing headers for the first time while reading
the module map, which often has very different paths from the include
scanning logic.
Using the name by which the file was accessed gets us one step closer to
the right solution, which is using a FileName abstraction that decouples
the name by which a file was accessed from the FileEntry.

redefinitions of that namespace have already been loaded. When writing out the
names in a namespace, if we see a name that is locally declared and had
imported declarations merged on top of it, export the local declaration as the
lookup result, because it will be the most recent declaration of that entity in
the redeclaration chain of an importer of the module.

Similar approach to the set1 intrinsics is used: implement in terms of vector
initializers and then ensure with an LLVM test that a broadcast is generated
at the end.

Summary:
This patch adds a runtime check verifying that functions
annotated with "returns_nonnull" attribute do in fact return nonnull pointers.
It is based on suggestion by Jakub Jelinek:

C++11 allows this qualifiers to exist on function types when used in
template arguments. Previously, I believed it wasn't possible because
MSVC rejected declarations like: S<int () const &> s;
However, it turns out MSVC properly allows them in using declarations;
updated clang to be compatible with this mangling.

We already verified the primary module map file (either the one that
defines the top-level module, or the one that allows inferring it if it
is an inferred framework module). Now we also verify any other module
map files that define submodules, such as when there is a
module.private.modulemap file.

According to the gcc docs, -include uses the current working directory
for the lookup instead of the main source file.
This patch gets rid of NormalizeIncludePath (which relied on an
implementation detail of FileManager / FileEntry for the include path
logic to work), and instead hands the correct lookup information down to
LookupFile.
This will allow us to change the FileEntry's behavior regarding its Name
caching.

it. Diagnose with recovery if it appears after a function parameter that was
obviously supposed to be a parameter pack. Otherwise, warn if it immediately
follows a function parameter pack, because the user most likely didn't intend
to write a parameter pack followed by a C-style varargs ellipsis.
This warning can be syntactically disabled by using ", ..." instead of "...".

anyway. If -ast-dump *is* also provided, then dump the AST declarations as well
as the lookup results. This is invaluable for cross-correlating the lookup
information with the declarations actually found.

Clang used a custom implementation of lookup when handling designated
initializers. The custom code was not particularly optimized and relied
on standard lookup for typo-correction anyway.
This custom code has to go, it doesn't properly support MSVC-style
anonymous structs embedded inside other records; replace it with the
typo-correction path.
This has the side effect of speeding up semantic handling of the fields
for a designated initializer while simplifying the code at the same
time.
This fixes PR20573.

In cases like:
struct C { ~C(); }
void f(C c = C());
void t() {
f();
}
We currently do not add the CXXBindTemporaryExpr for the temporary (the
code mentions that as the default parameter expressions are owned by
the declaration, we'd otherwise add the same expression multiple times),
but we add the temporary destructor pointing to the CXXBindTemporaryExpr.
We need to fix that before we can re-enable the assertion.

We had two bugs:
- We wouldn't properly warn when a struct/union/enum was mentioned
inside of a record definition if no declarator was provided. We
should have mentioned that this declaration declares nothing.
- We didn't properly support Microsoft's extension where certain
declspecs without declarators would act as anonymous structs/unions.
* We completely ignored the case where such a declspec could be a
union.
* We didn't properly handle the case where a record was defined inside
another record:
struct X {
int a;
struct Y {
int b;
};
};

hidden. Otherwise, NamedDecl::declarationReplaces will drop one of the name
lookup entries, making the typedef effectively inaccessible from one of the
modules that declared it.

While the test was already requiring shell-preserves-root (such as the
internal shell), it wasn't aware that the MSYS 1.0 env command knows how
to expand root by itself!
From cmd.exe try:
env SDKROOT=/ cmd //c echo %SDKROOT%
And get:
C:/MINGW/MSYS/1.0
To be certain we have a good 'env' program the test now requires a shell.

I reverted one of the added tests from r215261 in r215274, since it
was failing on quite a few bots. It looks like this wasn't sufficient,
as we're still getting failures on windows, like the following:
http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/5378
I'm reverting this entire commit so the bots aren't blocked on these
failures.
This reverts commit r215261.
