--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.

This linker backend is still a work in progress but is
enough to link simple programs including linking against
library archives.

SymbolBody and Symbol were separated classes due to a historical reason.
Symbol used to be a pointer to a SymbolBody, and the relationship
between Symbol and SymbolBody was n:1.
r2681780 changed that. Since that patch, SymbolBody and Symbol are
allocated next to each other to improve memory locality, and they have
1:1 relationship now. So, the separation of Symbol and SymbolBody no
longer makes sense.
This patch merges them into one class. In order to avoid updating too
many places, I chose SymbolBody as a unified name. I'll rename it Symbol
in a follow-up patch.

New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

The /appcontainer flag was added in r299728, and the lib.exe dependency
for creating import libraries was removed in r275242. Update the docs
accordingly.
The PDB support also needs updating, but I'll leave that for someone
who's more familiar with the current status (probably rnk).

Looks like it is not allowed to have an .rst file in this directory
that does not belong to a document tree. I don't know why. This patch
adds a file back to fix a bot.
