LLD is a multi-threaded program. errs() or outs() are not guaranteed
to be thread-safe (they are actually not).
LLD's message(), log() or error() are thread-safe. We should use them.

Summary: This copies over some functionality we have in ELF/Error.{cpp,h} and makes it available in COFF/Error.{cpp,h}

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.

This has a few advantages
* Less C++ code (about 300 lines less).
* Less machine code (about 14 KB of text on a linux x86_64 build).
* It is more debugger friendly. Just set a breakpoint on the exit function and
you get the complete lld stack trace of when the error was found.
* It is a more robust API. The errors are handled early and we don't get a
std::error_code hot potato being passed around.
* In most cases the error function in a better position to print diagnostics
(it has more context).

Instead of returning non-categorized errors, return categorized errors.
All uses of make_dynamic_error_code are removed.
Because we don't have error reporting mechanism, I just chose to print out
error messages to stderr, and then return an error object. Not sure if
that's the right thing to do, but at least it seems practical.
