We have a few functions that virtually all command wants to run on
process startup/shutdown. This patch adds InitLLVM class to do that
all at once, so that we don't need to copy-n-paste boilerplate code
to each llvm command's main() function.

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.

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.

looking for it along $PATH. This allows installs of LLVM tools outside of
$PATH to find the symbolizer and produce pretty backtraces if they crash.

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.

Take a StringRef instead of a "const char *".
Take a "std::error_code &" instead of a "std::string &" for error.
A create static method would be even better, but this patch is already a bit too
big.

Input YAML file might contain multiple object file definitions.
New option `-docnum` allows to specify an ordinal number (starting from 1)
of definition used for an object file generation.

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.

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

See the comment in yaml2obj.cpp for why this is currently needed.
Eventually we can get rid of this, but for now it is needed in order to
make forward progress with adding ELF support, and should be
straightforward to remove later.
Also, preserve the default of COFF, to avoid breaking existing tests.
This policy can easily be changed later though.

The alignment is just a byte in the middle of Characteristics, not an
independent flag. Making it an independent field in the yaml
representation makes it more yamlio friendly.

The COFFParser now contains only a COFFYAML::Object and the string table
(which is recomputed, not serialized).
The structs in COFFParser now all begin with a Header field with what is
actually on the COFF object. The other fields are things that are semantically
part of the struct (relocations in a section for exmaple), but are not actually
represented that way in the object file.
llvm-svn: 180134
Instead, use MappingNormalization to directly parse COFF::header. Also change
the naming convention of the helper classes to be a bit shorter.
