Fix `MDScope::getFile()` so that it correctly returns a valid `MDFile`
even when it's an instance of `MDFile`. This logic is necessary because
of r230057. I'm working on moving the new hierarchy into place
out-of-tree (on track to commit Monday morning, BTW), and this was
exposed by a few failing tests.

The SDK is insufficient to really build much. The builtins can be built
standalone now which is what the stub SDK was meant to permit. Remove the
unnecessary files.

Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.
This patch adds proper error handling so that we can know exactly
what went wrong.

MSVCRT 12.0 introduces better compatibility for C99. This includes a number of
math routines that were previously undefined. Use the crtversion.h header to
detect the version of MSVCRT being targeted and avoid re-declaring the
variables.
Since copysign has been introduced in MSVCRT, importing the definition via using
makes it difficult to provide overloads (due to minor differences between
throw () and noexcept. Avoid defining the overloads on newer MSVCRT
targets.

Level 1 should abort for all instructions but call/terminators/args.
Instead it was aborting only if the level was > 2

When using SetConsoleTextAttribute() to set the foreground or
background color, if you don't explicitly set both colors, then
a default value of black will be chosen for whichever you don't
specify a value for.
This is annoying when you have a non default console background
color, for example, and you try to set the foreground color.
This patch gets the existing fg/bg color and when you set one
attribute, sets the opposite attribute to its existing color
prior to comitting the update.

Leaving empty blocks around just opens up a can of bugs like PR22704. Deleting
them early also slightly simplifies code.
Thanks to Sanjay for the IR test case.

Patch by Evangelos Foutras:
r220899 started using ocamlfind to build the OCaml bindings but
docs/Makefile still contains references to the OCAMLDOC macro which
is no longer being defined. The result is that OCaml documentation
isn't generated/installed.

On OS X, if you don't have a full Xcode installation, but just the Command Line Tools package, xcrun and xcodebuild don't return a valid SDK root path. In these cases, let's use "/" as the SDK root (which is where the headers and libraries are installed).

All of the cases were just appending from random access iterators to a
vector. Using insert/append can grow the vector to the perfect size
directly and moves the growing out of the loop. No intended functionalty
change.

The syscall function itself is declared in <unistd.h>
Compiling compiler-rt with -Werror-implicit-function-declaration will
cause a build failure. This change fixes it.

The support for the LSB eh_frame_hdr extension was overzealous in trying to
include headers. Be more careful to permit building on Darwin.

It turns out the naming of inserted phis and selects is sensative to the order in which two sets are iterated. We need to nail this down to avoid non-deterministic output and possible test failures.
The modified test is the one I first noticed something odd in. The change is making it more strict to report the error. With the test change, but without the code change, the test fails roughly 1 in 5. With the code change, I've run ~30 runs without error.
Long term, the right fix here is to adjust the naming scheme. I'm checking in this hack to avoid any possible non-determinism in the tests over the weekend. HJust because I only noticed one case doesn't mean it's actually the only case. I hope to get to the right change Monday.
std->llvm data structure changes bugfix change #3

clang-3.5+ outputs FullDebugInfo by default for Darwin/FreeBSD targets.
Other targets do not, which causes several tests to fail. This flag
enables FullDebugInfo for all targets.
Fixes the following tests:
TestCallStdStringFunction.py
TestDataFormatterSkipSummary.py
TestDataFormatterStdIterator.py
TestDataFormatterStdList.py
TestDataFormatterStdString.py
TestSBValuePersist.py
TestStringPrinter.py

dynamic classes in the translation unit and check whether each one's key
function is defined when we got to the end of the TU (and when we got to the
end of each module). This is really terrible for modules performance, since it
causes unnecessary deserialization of every dynamic class in every compilation.
We now use a much simpler (and, in a modules build, vastly more efficient)
system: when we see an out-of-line definition of a virtual function, we check
whether that function was in fact its class's key function. (If so, we need to
emit the vtable.)

Inserting into a DenseMap you're iterating over is not well defined. This is unfortunate since this is well defined on a std::map.
"cleanup per llvm code style standards" bug #2
llvm-svn: 230827
This class is responsible for getting the linked data to the
disk in the appropriate form. Today it it an empty shell that
just instantiates an MC layer.
As we do not put anything in the resulting file yet, we just
check it has the right architecture (and check that -o does
the right thing).
To be able to create all the components, this commit adds a
few dependencies to llvm-dsymutil, namely all-targets, MC and
AsmPrinter.
Also add a -no-output option, so that tests that do not need
the binary result can continue to run even if they do not have
the required target linked in.
