Summary:
This patch adds support for merged arguments (e.g. -SW == -S -W) for llvm-readelf.

No changes are intended for llvm-readobj. There are a few short flags (-sd, -sr, -st, -dt) that would conflict with grouped single letter flags, and having only some grouped flags might be confusing. So, allow merged flags for readelf compatibility, but force separate args for llvm-readobj. From what I can tell, these two-letter flags are only used with llvm-readobj, not llvm-readelf.

Summary:
The test uses `nullptr` which can break running the test if the
compiler happens to be using something older than C++11 as the default
language standard. Avoid this by explicitly setting the standard.

This patch attempts to redo what was tried in r278783, but was reverted.

These intrinsics should be available on non-windows platforms with "xsave" feature check. But on Windows platforms they shouldn't have feature check since that's how MSVC behaves.

I've moved the forward declarations from intrin.h to immintrin.h to match the MSDN documentation and used that as the header file for the MS builtin.

I'm not super happy with this implementation, and I'm open to suggestions for better ways to do it.

Jordan Rupprecht [Mon, 14 Jan 2019 21:11:46 +0000 (21:11 +0000)]
[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.
