For LLVM_DIAGNOSTIC_DIR we want to create a subdirectory while for
DSYMUTIL_REPRODUCER_PATH we want to use the directory specified. The
latter makes writing a test a whole lot easier. Keep both to support
both scenarios.
Fix a assertion in dsymutil coming from the Reproducer/FileCollector.
When TMPDIR is empty, the root becomes a relative path, triggering an
assertion when adding a relative path to the VFS mapping. This patch
fixes the issue by resolving the relative path and also moves the
assertion up to make it easier to diagnose these issues in the future.

Automatically generate a reproducer when dsymutil crashes. We already
support generating reproducers with the --gen-reproducer flag, which
emits a reproducer on exit. This patch adds support for doing the same
on a crash and makes it the default behavior.

This reverts commit fd4808887ee47f3ec8a030e9211169ef4fb094c3.
This patch causes gcc to issue a lot of warnings like:
warning: base class ‘class llvm::MCParsedAsmOperand’ should be
explicitly initialized in the copy constructor [-Wextra]
Reproducer.cpp:70:12: error: could not convert ‘Repro’ from
‘std::unique_ptr<llvm::dsymutil::ReproducerGenerate,
std::default_delete<llvm::dsymutil::ReproducerGenerate> >’ to
‘llvm::Expected<std::unique_ptr<llvm::dsymutil::Reproducer> >’
Add support for generating a dsymutil reproducer. The result is a folder
containing all the object files for linking.
When --gen-reproducer is passed, dsymutil uses a FileCollectorFileSystem
which keeps track of all the files used by dsymutil. These files are
copied into a temporary directory when dsymutil exists.
When this path is passed to --use-reproducer, dsymutil uses a
RedirectingFileSystem that will use the files from the reproducer
directory instead of the actual paths. This means you don't need to mess
with the OSO path prefix.
