Clang warns that a profile is out-of-date if it can't find a profile
record for any function in a TU. This warning became noisy after llvm

To fix this, this patch changes the existing profile out-of-date warning

data. Further, it introduces a new, off-by-default warning about missing
function data (-Wprofile-instr-missing).

[CMake] Use object library to build the two flavours of Polly.
Polly comes in two library flavors: One loadable module to use the
LLVM framework -load mechanism, and another one that host applications
can link to. These have very different requirements for Polly's

The loadable module assumes that all its LLVM dependencies are already
available in the address space of the host application, and is not allowed
to bring in its own copy of any LLVM library (including the NVPTX
backend in case of Polly-ACC).
The non-module library is intended to be linked to using
target_link_libraries. CMake would then resolve all of its dependencies,
including NVPTX and ensure that only a single instance of each library
will be used.

Turn DISubprogram into a variable-length node.
DISubprogram currently has 10 pointer operands, several of which are

DISubprogram by rearranging the operands such that containing type,
template params, and thrown types come last, and are only allocated
when they are non-null (or followed by non-null operands).
This patch also eliminates the entirely unused DisplayName operand.
This saves up to 4 pointer operands per DISubprogram. (I tried

Don't accept -std= values that would switch us to a different source language.
We already prohibited this in most cases (in r130710), but had some bugs in our
enforcement of this rule. Specifically, this prevents the following
combinations:
* -x c -std=clN.M, which would previously effectively act as if -x cl were
used, despite the input being a C source file. (-x cl -std=cNN continues
to be disallowed.)
* -x c++ -std=cuda, which would previously select C++98 + CUDA, despite that
not being a C++ standard. (-x cuda -std=c++NN is still permitted, and
selects CUDA with the given C++ standard as its base language.
-x cuda -std=cuda is still supported with the meaning of CUDA + C++98.)
* -x renderscript -std=c++NN, which would previously form a hybrid "C++ with
RenderScript extensions" language. We could support such a thing, but
shouldn't do so by accident.

Summary:
LLVM r300140 changed the layout and field names of __compressed_pair, which

This patch attempts to fix these formatters by having them interogate the

variants, then access them accordingly.

Re-landing IPv6 support for LLDB Host
This support was landed in r300579, and reverted in r300669 due to failures on the bots.
The failures were caused by sockets not being properly closed, and this updated version of the patches should resolve that.
Summary from the original change:
This patch adds IPv6 support to LLDB/Host's TCP socket implementation. Supporting IPv6 involved a few significant changes to the implementation of the socket layers, and I have performed some significant code cleanup along the way.
This patch changes the Socket constructors for all types of sockets to not create sockets until first use. This is required for IPv6 support because the socket type will vary based on the address you are connecting to. This also has the benefit of removing code that could have errors from the Socket subclass constructors (which seems like a win to me).
The patch also slightly changes the API and behaviors of the Listen/Accept pattern. Previously both Listen and Accept calls took an address specified as a string. Now only listen does. This change was made because the Listen call can result in opening more than one socket. In order to support listening for both IPv4 and IPv6 connections we need to open one AF_INET socket and one AF_INET6 socket. During the listen call we construct a map of file descriptors to addrin structures which represent the allowable incoming connection address. This map removes the need for taking an address into the Accept call.
This does have a change in functionality. Previously you could Listen for connections based on one address, and Accept connections from a different address. This is no longer supported. I could not find anywhere in LLDB where we actually used the APIs in that way. The new API does still support AnyAddr for allowing incoming connections from any address.
The Listen implementation is implemented using kqueue on FreeBSD and Darwin, WSAPoll on Windows and poll(2) everywhere else.

Add support for DW_TAG_thrown_type.
For Swift we would like to be able to encode the error types that a
function may throw, so the debugger can display them alongside the
function's return value when finish-ing a function.
DWARF defines DW_TAG_thrown_type (intended to be used for C++ throw()
declarations) that is a perfect fit for this purpose. This patch wires
up support for DW_TAG_thrown_type in LLVM by adding a list of thrown
types to DISubprogram.
To offset the cost of the extra pointer, there is a follow-up patch
that turns DISubprogram into a variable-length node.

Create an OutputSection for each non-empty OutputSectionCommand.
We were already pretty close, the one exception was when a name was
reused in another SECTIONS directive:
SECTIONS {
.text : { *(.text) }
.data : { *(.data) }
}
SECTIONS {
.data : { *(other) }
}
In this case we would create a single .data and magically output
"other" while looking at the first OutputSectionCommand.
We now create two .data sections. This matches what gold does. If we
really want to create a single one, we should change the parser so that
the above is parsed as if the user had written
SECTIONS {
.text : { *(.text) }
.data : { *(.data) *(other)}
}
That is, there should be only one OutputSectionCommand for .data and
it would have two InputSectionDescriptions.

important step in allowing assignAddresses to operate just on the
