DebugInfo: Shrink pubnames/pubtypes in the presence of type units by only emitting pub sections for compile units

Fix issues in the NamedMDNode operand iterator, including those pointed out by
Chandler in review.

Change the tag on this iterator to bidir and implement enough operators to make it true.
It ought to be possible to make this truly random access if anyone cares enough.

[Layering] Move InstVisitor.h into the IR library as it is pretty
obviously coupled to the IR.

[Layering] Sink Linker.h into a Linker subdirectory to make it
consistent with every other sub-library header in LLVM.

[Layering] Move GVMaterializer.h into the IR library where its
implementation already lived.

After this commit, the only IR-library headers in include/llvm/* are
ones related to the legacy pass infrastructure that I'm planning to
leave there until the new one is farther along.

The only other headers at the top level are linking and initialization
aids that aren't really libraries but just headers.

[Modules] Fix a layering issue that is actually impacting the modules
selfhost.

The 'Core.h' C-API header is part of the IR LLVM library. (One might
even argue it should be called IR.h, but that's a separate point.) We
can't include it into a Support header without violating the layering,
and in a way that breaks modules. MemoryBuffer's opaque C type was being
defined in the Core.h C-API header despite being in the Support library,
and thus we ended up with this weird issue.

It turns out that there were other constructs from the Support library
in the Core.h header. This patch lifts all of them into Support.h and
then includes that into Core.h.

The only possible fallout is if someone was including Support.h and
relying on Core.h to be visible for their own uses. Considering the
narrow interface actually provided by the C-API for the Support library,
this seems a very, very unlikely mistake.

DebugInfo: Tag units as having been indexed in GNU pubnames by using a DW_AT_GNU_pubnames of DW_FORM_flag(_present) rather than sec_offsets to the pubnames/types sections

This is consistent with GDB ToT and reduces the number of relocations in
(type and compile) units, substantially reducing relocations and debug
size in fission + type units builds.

Replace OwningPtr<T> with std::unique_ptr<T>.

This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.
