a9f9cbaaf6 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.

714e82ffc5 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.

ad911dcfea Option parsing: add support for alias arguments.
This makes option aliases more powerful by enabling them to
pass along arguments to the option they're aliasing.

For example, if we have a joined option "-foo=", we can now
specify a flag option "-bar" to be an alias of that, with the
argument "baz".

This is especially useful for the cl.exe compatible clang driver,
where many options are aliases. For example, this patch enables
us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to
"-Werror" (again, -W is a joined option).

045ec611a0 [Option] Add inclusion and exclusion flags to option parsing
Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.

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

High level discussion for clang-cl is here:

2da0e325fb Revert "[Option] Store arg strings in a set backed by a BumpPtrAllocator"
This broke clang's crash-report.c test, and I haven't been able to
figure it out yet.

This reverts commit r186319.

588e7b3d3d [Option] Store arg strings in a set backed by a BumpPtrAllocator
No functionality change.

This is preparing to move response file parsing into lib/Option so it
can be shared between clang and lld.  This change isn't just a
micro-optimization.  Clang's driver uses a std::set<std::string> to
unique arguments while parsing response files, so this matches that.

cd4d94dfeb Merge changes to clang's Driver code into LLVM's Option library
This is in preparation for switching the clang driver over to using LLVM's
Option library.  Richard Smith introduced most of these changes to the clang
driver in r167638.

5f5c383ef1 Resort the #include lines in include/... and lib/... with the
utils/sort_includes.py script.

Most of these are updating the new R600 target and fixing up a few
regressions that have creeped in since the last time I sorted the
includes.
