I accidentally combined this patch with one for adding more tests, they
should be separated.
This reverts commit 3da218a523be78df32e637d3446ecf97c9ea0465.

Summary:
Use the filepath used to open the archive member as the archive member
name instead of the file basename. This path might be absolute or
relative. This is important because the archive member name will show
up in the PDB, and we want our PDBs to look as much like MSVC's as
possible.
This also helps avoid an issue in our PDB module descriptor writing
code, which assumes that all module names are unique. Relative paths
still aren't guaranteed to be unique, but they're much better than
basenames, which definitely aren't unique.

This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

The fix was to use "SymbolName" when translating LLD's internal export
list to lib/Object's short export struct. The SymbolName reflects the
actual symbol name, which may include fastcall and stdcall mangling bits
not included in the /EXPORT or .def file EXPORTS name:

Original commit message:
This change is intended to use for LLD in D33183.
Problem we have in LLD when building .gdb_index is that we need to know section which address range belongs to.
Previously it was solved on LLD side by providing fake section addresses with use of llvm::LoadedObjectInfo
interface. We assigned file offsets as addressed. Then after obtaining ranges lists, for each range we had to find section ID's.
That not only was slow, but also complicated implementation and was the reason of incorrect behavior when
sections share the same offsets, like D33176 shows.
This patch makes DWARF parsers to return section index as well. That solves problem mentioned above.

I revisited Decompressor API (issue with it was triggered during D32865 review)
and found it is probably provides more then we really need.
Issue was about next method's signature:
Error decompress(SmallString<32> &Out);
It is too strict. At first I wanted to change it to decompress(SmallVectorImpl<char> &Out),
but then found it is still not flexible because sticks to SmallVector.
During reviews was suggested to use templating to simplify code. Patch do that.

Running `llvm-readobj -coff-directives msvcrt.lib` resulted in this error:
Invalid data was encountered while parsing the file
This happened because some of the object files in the archive have empty
`.drectve` sections. These empty sections result in a `parse_failed` error being
returned from `COFFObjectFile::getSectionContents()`, which in turn caused
`llvm-readobj` to stop. With this change, `getSectionContents` now returns
success, and like before the resulting array is empty.

This is motivated by https://reviews.llvm.org/D32488 where I am trying
to add printing of the section type for incompatible sections to LLD
error messages. This patch allows us to use the same code in
llvm-readobj and LLD instead of duplicating the function inside LLD.

Marking them as used causes them to be considered visible outside of LTO. This
prevents the symbols from being internalized or discarded, either by GlobalDCE
or by summary-based dead stripping in ThinLTO.
This change makes it unnecessary to add these symbols to llvm.compiler.used
in the backend, as the symbols are kept alive by virtue of being external,
so remove the backend code that handles that.
Fixes PR32798.
