Currently, our address-of overload machinery will only allow implicit

void f(int) __attribute__((overloadable));
void f(double) __attribute__((overloadable, enable_if(0, "")));
void *fp = f; // OK. This is C and the target is void*.
void (*fp2)(void) = f; // Error. This is C, but the target isn't void*.

Drop comdats from the dst module if they are not selected.

they operate one module at a time.
This means they can copy a GV to the destination module that should not

precedence.
We already handled cases like a strong GV replacing a weak for example.
One case that is not currently handled is a comdat replacing another.
This doesn't happen in ELF, but with COFF largest selection kind it is
possible.
In "llvm-link a.ll b.ll" if the selected comdat was from a.ll,

[clang-tidy] Fix redundant-string-cstr check with msvc 14 headers.
Summary:
The string constructors are not defined using optional parameters and are not recognize by the checker.
The constructor defined in the MSVC header is defined with 1 parameter. Therefore, patterns are not recognized by the checker.
The current patch add support to accept constructor with only one parameter.
Repro on a Visual Studio 14 installation with the following code:
```
void f1(const std::string &s) {
f1(s.c_str());
}
```
In the xstring.h header, the constructors are defined this way:
```
basic_string(const _Myt& _Right) [...]
basic_string(const _Myt& _Right, const _Alloc& _Al) [...]
```
The CXXConstructExpr to recognize only contains 1 parameter.

[clang-tidy] Skip reporting of not applicable fixes.
Summary:
Invalid source location are causing clang-tidy to crash when manipulating an invalid file.
Macro definitions on the command line have locations in a virtual buffer and therefore
don't have a corresponding valid FilePath.
A recent patch added path conversion to absolute path. As the FilePath may now be empty,
the result of makeAbsolutePath may incorrectly be the folder WorkingDir. The crash occurs
in getLocation which is not able to find the appropriate FileEntry (null pointer).
```
SmallString<128> FixAbsoluteFilePath = Fix.getFilePath();
Files.makeAbsolutePath(FixAbsoluteFilePath);
FixLoc = getLocation(FixAbsoluteFilePath, Fix.getOffset());
```
With relative path, the code was not crashing because getLocation was skipping empty path.
Example of code:
```
int main() { return X; }
```
With the given command-line:
```
clang-tidy test.cc --checks=misc-macro-* -- -DX=0+0

Summary:
After patch https://lkml.org/lkml/2015/12/21/340 is introduced in
linux kernel, the random gap between stack and heap is increased
from 128M to 36G on 39-bit aarch64. And it is almost impossible
to cover this big range. So I think we need to disable randomized
virtual space on aarch64 linux.

Use owning pointers instead of raw pointers for Atom's to fix leaks.
This is a re-commit of r264022 with a fix for MSVC. The issue there was
that the code was running DefinedAtom::~Atom() for some value and instead
needed to cast to Atom before running ~Atom. Original commit message follows.
Currently each File contains an BumpPtrAllocator in which Atom's are
allocated. Some Atom's contain data structures like std::vector which
leak as we don't run ~Atom when they are BumpPtrAllocate'd.
Now each File actually owns its Atom's using an OwningAtomPtr. This
is analygous to std::unique_ptr and may be replaced by it if possible.
An Atom can therefore only be owned by a single File, so the Resolver now
moves them from one File to another. The MachOLinkingContext owns the File's
and so clears all the Atom's in ~MachOLinkingContext, then delete's all the
File's. This makes sure all Atom's have been destructed before any of the
BumpPtrAllocator's in which they run have gone away.
Should hopefully fix the remaining leaks. Will keep an eye on the bots to
make sure.
