Somehow all the functionality to write PDB files got removed,
probably accidentally when uploading the patch perhaps the wrong
one got uploaded. This re-adds all the code, as well as the
corresponding test.

The NewArchiveIterator class has a problem: it requires too much context. Any
memory buffers added to the archive must be stored within an Archive::Member,
which must have an associated Archive. This makes it harder than necessary
to create new archive members (or new archives entirely) from scratch using
memory buffers.
This patch replaces NewArchiveIterator with a NewArchiveMember class that
stores just the memory buffer and the information that goes into the archive
member header.

This fixes pr28072.
The point, as Duncan pointed out, is that the file is already
partially linked by just reading it.
Long term I think the solution is to make metadata owned by the module
and then the linker will lazily read it and be in charge of all the
linking. Running a verifier in each input will defeat the lazy
loading, but will be legal.
Right now we are at the unfortunate position that to support odr
merging we cannot verify the inputs, which mildly annoying (see test
update).

In -output-dir mode, file reports are placed into a "coverage"
directory. If filenames in the coverage mapping contain "..", they might
escape out of this directory.
Fix the problem by removing ".." from source filenames (expand the path
component).

- Add renderView{Header,Footer}, renderLineSuffix, and hasSubViews to
support creating tables with nested views.
- Move the 'Format' cl::opt to make it easier to extend.
- Just create one function view file, instead of overwriting the same
file for every new function. Add a regression test for this.

and its clients to use the new llvm::Error model for error handling.
Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all
interfaces there use the new llvm::Error model for return values.
In the two places it had if (!Parent) this is actually a program error so changed
from returning errorCodeToError(object_error::parse_failed) to calling
report_fatal_error() with a message.
In getObjectForArch() added error messages to its two llvm::Error return values
instead of returning errorCodeToError(object_error::arch_not_found) with no
error message.
For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in
Mach-O Universal Binaries that are supported are Mach-O files or archives with
Mach-O objects, updated their logic to generate an error when a slice contains
something like an ELF binary instead of ignoring it. And added a test case for
that.
The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is
the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs
Archive::create() to be changed from ErrorOr<...> to Expected<...> first,
which I’ll work on next.

allow a good error message to be produced.
I added the one test case that the object file tools could produce an error
message. The other two errors can’t be triggered if the input file is passed
through sys::fs::identify_magic(). But the malformedError("bad magic number")
does get triggered by the logic in llvm-dsymutil when dealing with a normal
Mach-O file. The other "File too small ..." error would take a logic error
currently to produce and is not tested for.

binutils ar uses -plugin to specify the LTO plugin, but LLVM doesn't
need this as it doesn't use a plugin for LTO. Accepting (and ignoring)
the option allows interoperability with existing build systems and
make downstream consumers life much easier.
No objections from Rafael on this change.

Summary:
Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that.
Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are:
!ELF
!COFF
!mach-o
!fat-mach-o
I have a corresponding patch that is quite large that fixes up all the in-tree test cases.

If a sub-view has already been rendered, it's helpful to re-render the
expansion site before rendering the next expansion view. Make this fact
explicit in the rendering interface, instead of hiding it behind an
awkward Optional<LineRef> parameter.

a good error message to be produced.
This is nearly the last libObject interface that used ErrorOr and the last one
that appears in llvm/include/llvm/Object/MachO.h . For Mach-O objects this is
just a clean up because it’s version of getSymbolAddress() can’t return an
error.
I will leave it to the experts on COFF and ELF to actually add meaning full
error messages in their tests if they wish. And also leave it to these experts
to change the last two ErrorOr interfaces in llvm/include/llvm/Object/ObjectFile.h
for createCOFFObjectFile() and createELFObjectFile() if they wish.
Since there are no test cases for COFF and ELF error cases with respect to
getSymbolAddress() in the test suite this is no functional change (NFC).

A SourceName can be a file or a function. It makes sense to attach this
information to a SourceCoverageView, seeing as views (1) already point
to the text corresponding to the relevant source code and (2) are
already used to render that text along with the SourceNames.
This is a nice cleanup which is independent of the upcoming html patch.
While we're at it, document the fields in SourceCoverageView.

Pull LineCoverageInfo out of SourceCoverageView and rename it so that it
doesn't conflict with another class of the same name in
CoverageSummaryInfo.h.
This cuts down on the amount of code we have to move into a `protected`
section of SourceCoverageView for the upcoming html patch. It also makes
the code a bit clearer: having two LineCoverageInfo's is strange.

32-bit Mach headers don't have reserved fields. When generating the
mapping for 32-bit headers leaving off the reserved field will result in
parse errors if the field is present in the yaml.
Added a CHECK-NOT line to ensure that mach_header.yaml isn't adding a
reserved field, and a test to ensure that the parser error gets hit with
32-bit headers.

This flag was introduced in r269655 with the new diagnostic handler for llc. Its
purpose was to keep the old behavior for some of the tests that didn't recover
well after an error. Those tests have been fixed, so now it's safe to remove the
flag entirely.
