When in-tree libcxx is selected as the sanitizer C++ ABI, use libcxx
targets rather than libcxxabi and libunwind, since those may not be
available on all platforms (Windows for example).

Disallow this meaningless combination. Doing so simplifies analysis
of LLVM code w.r.t t DLL storage-class, and prevents mistakes with
DLL storage class.

- Change the assembler to reject DLL storage class on symbols with
  local linkage.
- Change the bitcode reader to clear the DLL Storage class when the
  linkage is local for auto-upgrading
- Update LangRef.

There is an existing restriction on non-default visibility and local
linkage which this is modelled on.

This is a first step towards fully implementing the new dimension
level types and properties, illustrating with a fully functional
sorted COO of any dimension. Note that the sparsification part is
pretty complete. The required parts in the runtime support library
have been kept to a minimum, to avoid huge conflicts with Wren's
ongoing refactoring. The missing parts will be filled in later.

Previously, the SparseTensorUtils.cpp library contained a C++ core implementation, but hid it in an anonymous namespace and only exposed a C-API for accessing it. Now we are factoring out that C++ core into a standalone C++ library so that it can be used directly by downstream clients (per request of one such client). This refactoring has been decomposed into a stack of differentials in order to simplify the code review process, however the full stack of changes should be considered together.

This change exposes the ceil library function for HLSL,
excluding long, int, and long long doubles.
Ceil is supported for all scalar, vector, and matrix types.

Long and long long double support is missing in this patch because those types
don't exist in HLSL. Int is missing because the ceil function only works on floating type arguments.

The full documentation of the HLSL ceil function is available here:

In combineOr (X86ISelLowering.cpp) there is a DAG combine that rewrite
a "(0 - SetCC) | C" pattern into something simpler given that a LEA
can be used. Another requirement is that C has some specific value,
for example 1 or 7. When checking those requirements the code used a
32-bit unsigned variable to store the value of C. So for a 64-bit OR
this could miscompile in case any of the 32 most significant bits in
C were non zero.

This patch adds fixes the bug by using a large enough type for the
C value.

The faulty code seem to have been introduced by commit 9bceb898
