Fix PR17239 by changing the semantics of the RemainingArgsClass Option kind

This patch contains the LLVM side of the fix of PR17239.

This bug that happens because the /link (clang-cl.exe argument) is
marked as "consume all remaining arguments". However, when inside a
response file, /link should only consume all remaining arguments inside
the response file where it is located, not the entire command line after
expansion.

My patch will change the semantics of the RemainingArgsClass kind to
always consume only until the end of the response file when the option
originally came from a response file. There are only two options in this
class: dash dash (--) and /link.

Option parsing: support case-insensitive option matching.

Link.exe's command line options are case-insensitive. This patch
adds a new attribute to OptTable to let the option parser to compare
options, ignoring case.

Command lines are generally case-insensitive on Windows. CL.exe is an
exception. So this new attribute should be useful for other commands
running on Windows.

Options: Add new option kind that consumes remaining arguments

This adds KIND_REMAINING_ARGS, a class of options that consume
all remaining arguments on the command line.

This will be used to support /link in clang-cl, which is used
to forward all remaining arguments to the linker.

It also allows us to remove the hard-coded handling of "--",
allowing clients (clang and lld) to implement that functionality
themselves with this new option class.

Option parsing: recognize the special -- token

Everything that comes after -- should be treated as a filename. This
enables passing in filenames that would otherwise be conflated with
command-line options.

This is especially important for clang-cl which supports options
starting with /, which are easily conflatable with Unix-style
path names.

[Option] Add inclusion and exclusion flags to option parsing

Summary:
This allows the clang driver to put MSVC compatible options in the same

Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.
