We'd like to keep the clang-cl self-host working until we implement
MSVC-compatible RTTI.

DWARF discriminators are used to distinguish multiple control flow paths
on the same source location. When this happens, instructions across
basic block boundaries will share the same debug location.
This pass detects this situation and creates a new lexical scope to one
of the two instructions. This lexical scope is a child scope of the
original and contains a new discriminator value. This discriminator is
then picked up from MCObjectStreamer::EmitDwarfLocDirective to be
written on the object file.
This fixes http://llvm.org/bugs/show_bug.cgi?id=18270.

predicate. The wrapper used by SetVector was erroneously requiring an
adaptable predicate. It has been fixed and we really don't want to
require an indirect call for every predicate evaluation.

The module LLVMPolly.so links to that. There is really no reason to build a
large number of mini-libraries here, especially as we do have dependences
between the libraries that are not properly handled and that make linking fail
on darwin.

remove_if that its predicate is adaptable. We don't actually need this,
we can write a generic adapter for any predicate.
This lets us remove some very wrong std::function usages. We should
never be using std::function for predicates to algorithms. This incurs
an *indirect* call overhead for every evaluation of the predicate, and
makes it very hard to inline through.

Serialized diagnostics were accidentally using the AST diagnostic level values
rather than a dedicated stable enum, so the addition of "remark" broke the
reading of existing serialized diagnostics files. I've added a .dia file
generated from Xcode 5's Clang to make sure we don't break this in the future.

Breaks the MSVC build.

With C++11 we finally have a standardized way to specify atomic operations. Use
them to replace the existing custom implemention. Sadly the translation is not
entirely trivial as std::atomic allows more fine-grained control over the
atomicity. I tried to preserve the old semantics as well as possible.

It's easy to copy unintentionally when using 'auto', particularly inside
range-based for loops. Best practise is to use 'const&' unless there's
a good reason not to.

The current coding standards restrict the use of struct to PODs, but no
one has been following them. This patch updates the standards to
clarify when structs are dangerous and describe common practice in LLVM.

The shared library generated by autoconf will now be called
libLLVM-$(VERSION_MAJOR).$(VERSION_MINOR).$(VERSION_PATCH)$(VERSION_SUFFIX).so
and a symlink named
libLLVM-$(VERSION_MAJOR).$(VERSION_MINOR)$(VERSION_SUFFIX).so will
also be created in the install directory.

Summary:
Previously llvm-config --system-libs would print something like:
$ llvm-config --system-libs
-lz -ltinfo -lrt -ldl -lm
Now we don't emit blank line. Functionality is unchanged otherwise, in
particular llvm-config --libs --system-libs still emits the LLVM libraries
and the system libraries on different lines.

Summary:
Parts of the compiler still believed MSA load/stores have a 16-bit offset when
it is actually 10-bit. Corrected this, and fixed a closely related issue this
uncovered where load/stores with 10-bit and 12-bit offsets (MSA and microMIPS
respectively) could not load/store using offsets from the stack/frame pointer.
They accepted frameindex+offset, but not frameindex by itself.
