- Support comma joined options which magically turn into multiple
value arguments (e.g., -Wl,)
- Split out separate Arg::render routine for when an argument is
being rendered as an input (as opposed to in its original form).
- Add option flag for options which should be rendered without the
option when they are used as an input (e.g., -Xlinker or -o).
- Support -weak-l..., -weak_framework, and -weak_library.

- Some things are still hardcoded, and macosx-version-min comparison
isn't implemented, but otherwise this very closely matches gcc.
- The one exception is that arguments (like -framework or -Wl,) which are
treated as linker inputs instead of options are not being
forwarded yet.

"fake" options, allowing Tools to be oblivious to whether an argument
is real or synthetic. This kills off DerivedArg & a number of FIXMEs.

- Entry point is tools/ccc/xcc until we are a functional replacement
for ccc.
This is highly experimental (FIXME/LOC ratio of 3.4%), quite crufty,
and barely usable (and then only on my specific Darwin). However, many
of the right ideas are present, and it already fixes a number of
things gcc gets wrong.
The major missing component is argument translation for tools
(translating driver arguments into cc1/ld/as/etc. arguments). This is
a large part of the driver functionality and will probably double the
LOC, but my hope is that the current architecture is relatively
stable.
Documentation & motivation to follow soon...
