Previously, we had a loop to iterate over options starting with
`--plugin-opt=` and parse them by hand. But we can make OptTable
do that job for us.

This is most useful when using lld-link on a non-Win host (but it might become
useful on Windows too if lld also grows a fansi-escape-codes flag).
Also make the help for --color-diagnostic mention the valid values in ELF and
wasm, and print the flag name with two dashes in diags, since the one-dash form
is seen as a list of many one-letter flags in some contexts.

I tested that if I remove "elf" from the message, building a program
that uses libtool prints

but with this patch it still prints

Summary:
I noticed that the reproducers files I was getting from building CheriBSD
didn't work because the --sysroot option was not being rewritten. I've
updated the test to also verify that the rewritten path matches uses a
FileCheck capature instead of a {{.+}} regex

Summary:
This matches the behaviour of ld.bfd:

If scriptfile does not exist in the current directory, ld looks for it in
the directories specified by any preceding '-L' options. Multiple '-T'
options accumulate.

Summary:
The COFF linker and the ELF linker have long had similar but separate
Error.h and Error.cpp files to implement error handling. This change
introduces new error handling code in Common/ErrorHandler.h, changes the
COFF and ELF linkers to use it, and removes the old, separate
implementations.

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 --symbol-ordering-file path was not being rewritten in the response file when

Summary:
If the linker is invoked with `--chroot /foo` and `/bar/baz.o`, it
tries to read the file from `/foo/bar/baz.o`. This feature is useful
when you are dealing with files created by the --reproduce option.

This is a fix for Bugzilla 28579.
The problem is that in --reproduce links the file path in -o option is
copied verbatim. When "lld @response.txt" link is run against the
extracted test case, if -o contains anything other that a plain file
name, the link will likely fail because the target directory in -o may
not exists. Stripping the directory path will create the output file
in the top level test directory.

Previously, that was an alias to -color-diagnostics=auto. However,
Clang's -fcolor-diagnostics is an alias to -fcolor-diagnostics=always,
so that was confusing. This patch fixes that issue.

Previously, some errors that were checked before we set to
Config->ColorDiagnostics weren't colored. This patch moves the code
to set the variable so that such error messages are colored just like
other error messages.

I thought for a while about how to remove it, but it looks like we
can just copy the file for now. Of course I'm not happy about that,
but it's just less than 50 lines of code, and we already have
duplicate code in Error.h and some other places. I want to solve
them all at once later.

The feature is documented as
-----------------------------
The format of the dynamic list is the same as the version node
without scope and node name. See *note VERSION:: for more
information.
--------------------------------
And indeed qt uses a dynamic list with an 'extern "C++"' in it. With
this patch we support that
The change to gc-sections-shared makes us match bfd. Just because we
kept bar doesn't mean it has to be in the dynamic symbol table.
The changes to invalid-dynamic-list.test and reproduce.s are because
of the new parser.
The changes to version-script.s are the only case where we change
behavior with regards to bfd, but I would like to see a mix of
--version-script and --dynamic-list used in the wild before
complicating the code.

Previously, we have a lot of BumpPtrAllocators, but all these

This flag is implemented similarly to --reproduce in the ELF linker.
This patch implements /linkrepro by moving the cpio writer and associated
utility functions to lldCore, and using that implementation in both linkers.
One COFF-specific detail is that we store the object file from which the
resource files were created in our reproducer, rather than the resource
files themselves. This allows the reproducer to be used on non-Windows
systems for example.
