Jordan Rupprecht 93bfb99ffc [llvm-ar] Flatten thin archives.
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.

Owen Reynolds c443e7ef55 [llvm-ar] Access ADDLIB in llvm-ar via command line
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.

Reid Kleckner f6e8c4dd29 [llvm-ar] Extract objects to their basename in the CWD
This is helpful when extracting objects from archives produced by MSVC's
lib.exe, which users absolute paths to describe the archive members.

Saleem Abdulrasool aecbdf70bf Object: support empty UID/GID fields
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.

Chris Bieneman 8ff0c11357 [yaml2obj] Remove --format option in favor of YAML tags
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.
