[lld][MachO] Initial implementation of -flat_namespace and -undefined.
...
This is a basic initial implementation of the -flat_namespace and
-undefined options for LLD-darwin. It ignores several subtlties,
but the result is close enough that we can now link LLVM (but not
clang) on Darwin and pass all regression tests.

COFF: ICF should not merge sectinos if their alignments are not the same.
...
There's actually a room to improve this patch. Instead of not merging
sections that have different alignements, we can choose the section that
has the largest alignment requirement among all sections that are otherwise
considered the same. Then all section alignments are satisfied, so we can
merge them.
I don't know if that improvement could make any difference for real-world
input, so I'll leave it alone. Would be interesting to revisit later.

[ELF2] Fix binaries so they actually run on FreeBSD.
...
Since FreeBSD 4.1, the kernel expects binaries to be marked with
ELFOSABI_FREEBSD in the ELF header to exec() them. LLD unconditionally
sets OSABI to ELF_OSABINONE, and everything linked with it won't run
on FreeBSD (unless explicitly rebranded).
Example:
% ./aarch64-hello
ELF binary type "0" not known.
zsh: exec format error: ./aarch64-hello
FreeBSD could be modified to accept ELF_OSABINONE, but that would break all
existing binaries, so the kernel needs to support both ABINONE and ABIFREEBSD.
I plan to push this change in FreeBSD one day, which, unfortunately, is
not today. This code patches lld so it sets the header field correctly.
For completeness, the rationale of this change is explained in the FreeBSD
commit message, and it's apparently to pleasee binutils maintainers at the time.

[ELF2] Remove ignored options handling.
...
This was prematurely committed (and I take the blame for that).
Ideally, we want to support only ignored options that are really used
by somebody. Some of the options listed are not even supported by gold
(but only by ld.bfd), which says a lot about their "real-world" usefulness.
