--push-state implemented in this patch saves the states of --as-needed,
--whole-archive and --static. It saves less number of flags than GNU linkers.
Since even GNU linkers save different flags, no one seems to care about the
details. In this patch, I tried to save the minimal number of flags to not
complicate the implementation and the siutation.
I'm not personally happy about adding the --{push,pop}-state flags though.
That options seem too hacky to me. However, gcc started using the options
since GCC 8 when GNU ld is available at the build time. Therefore, lld
is no longer a drop-in replacmenet for GNU linker for that machine
without supporting the flags.

Also remove the space between --lto-O and value, as the option with a
space is not accepted at present.
Leave --opt-remarks-filename as it does not currently accept the = form.

The argument is section=address, not just address.
(For compatibility with GNU linkers we need to, but do not yet, accept
--section-start=section=address.)

We intend to maintain compatibility with GNU ld, and in the GNU world
long options are conventionally specified as --long-option=value. For
whatever reason GNU ld.bfd accepts both --long-option value and
--long-option=value, but documents the former. Follow suit.
Some lld long options do not accept the = form; this is probably a bug
to be fixed (along with a man page update).

Initial ld.lld.1 man page commit in r324512 crossed paths with r324502
which added --build-id=fast, allowing --build-id to be documented as a
synonym for --build-id=fast. Catch up with that change in the man page.

One of the FreeBSD requirements for enabling lld as the system linker is
that it has a man page. Other FreeBSD developers and I created one using
lld's --help output as a starting point. This is an expanded and
improved version of that.
This man page would benefit from additional content, but it provides
basic user-facing coverage of lld's options and serves as a good
starting point.
