Summary:
Normal behavior for GNU ar is to flatten thin archives when adding them to another thin archive, i.e. add the members directly instead of nesting the archive.
Some refactoring done as part of this patch to ease things:
- Consolidate `addMember`/`addLibMember` methods
- Rename `addMember` to `addChildMember` to make it more visibly different at the call site that an archive child is passed instead of a regular member
- Pass in a separate vector and splice it back into position instead of passing a vector + optional Pos (which makes expanding libs tricky)
This fixes PR37530 as raised by https://github.com/ClangBuiltLinux/linux/issues/279.

ADDLIB is called to add the contents of an archive to another archive.
Previously this was only accessible through the use of an MRI script.
With the use of a new "L" modifier, archive files can treated in the
manner above when using quick append.

Summary:
The POSIX spec says:
```
If the −t option is used with the −v option, the standard output format shall be:
"%s %u/%u %u %s %d %d:%d %d %s\n", <member mode>, <user ID>,
<group ID>, <number of bytes in member>,
<abbreviated month>, <day-of-month>, <hour>,
<minute>, <year>, <file>
where:
...
<abbreviated month>
Equivalent to the format of the %b conversion specification format in date.
<day-of-month>
Equivalent to the format of the %e conversion specification format in date.
<hour> Equivalent to the format of the %H conversion specification format in date.
<minute> Equivalent to the format of the %M conversion specification format in date.
<year> Equivalent to the format of the %Y conversion specification format in date.
```
This actually used to be the format printed by llvm-ar. It was apparently accidentally changed (see r207385 followed by comments in r207387). This makes it conform to GNU ar for easier replacement.

MRI scripts have two comment chars, * and ;, but only the latter was
supported before.
Also allow leading spaces before comment chars (and before any command
string), and allow comments after a command.

This allows syntax like:
$ llvm-ar -c -r -u file.a file.o
This is in addition to the other formats that are already supported:
$ llvm-ar cru file.a file.o
$ llvm-ar -cru file.a file.o

Most callers were not expecting the exit(0) and trying to exit with a
different value.
This also adds back the call to cl::PrintHelpMessage in llvm-ar.

This is helpful when extracting objects from archives produced by MSVC's
lib.exe, which users absolute paths to describe the archive members.

Normal archives do not have empty UID/GID fields. However, the Microsoft
Import library format is a customized archive (it just uses an alternate symbol
index format). When the import library is constructed by lib.exe, the UID and
GID fields are left empty. Do not abort on such an input.

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.

This adds some tests for the smarter llvm-ar selection mode as well as some
additional tests as per Rafael's post commit review comments.
