For testing purposes I need a way to build and install FileCheck and
yaml2obj. I had to choose between making FileCheck an LLVM tool and
making obj2yaml and yaml2obj utilities. I think the distinction is
rather arbitrary but my understanding is that tools are things meant for
the toolchain while utilities are more used for things like testing,
which is the case here.
The functional difference is that these tools now end up in the
${LLVM_UTILS_INSTALL_DIR}, which defaults to the ${LLVM_TOOLS_INSTALL_DIR}.
Unless you specified a different value or you added obj2yaml and
yaml2obj to ${LLVM_TOOLCHAIN_TOOLS}, this patch shouldn't change
anything.

Summary:
This patch adds the ability to read a yaml form of a minidump file and
write it out as binary. Apart from the minidump header and the stream
directory, only three basic stream kinds are supported:
- Text: This kind is used for streams which contain textual data. This
is typically the contents of a /proc file on linux (e.g.
/proc/PID/maps). In this case, we just put the raw stream contents
into the yaml.
- SystemInfo: This stream contains various bits of information about the
host system in binary form. We expose the data in a structured form.
- Raw: This kind is used as a fallback when we don't have any special
knowledge about the stream. In this case, we just print the stream
contents in hex.
For this code to be really useful, more stream kinds will need to be
added (particularly for things like lists of memory regions and loaded
modules). However, these can be added incrementally.

This was originally reverted because of some non-deterministic
failures on certain buildbots. Luckily ASAN eventually caught
this as a stack-use-after-scope, so the fix is included in
this patch.

Mostly this change adds support converting to and from
YAML which will allow us to write more test cases for
the WebAssembly MC and lld ports.
Better support for objdump, readelf, and nm will be in
followup CLs.
I had to update the two wasm test binaries because they
used the old style 'name' section which is no longer
supported.

This patch pulls the yaml2dwarf code out of yaml2obj into a new set of DWARF emitter functions in the DWARFYAML namespace. This will enable the YAML->DWARF code to be used inside DWARF tests by populating the DWARFYAML structs and calling the Emitter functions.

This abstracts the code for emitting DWARF binary from the DWARFYAML types into reusable interfaces that could be used by ELF and COFF.

Adding the initial files for adding MachO support to yaml2obj. Passing a MachO file will result in an error.
I will be implementing obj2yaml and yaml2obj for MachO in parallel so that one can be used to test the other.

Currently, only emitting the ELF header is supported (no sections or
segments).
The ELFYAML code organization is broadly similar to the COFFYAML code.
