incorrectly. I'm blanking on the smartest way to write this search,
but we should just do the right thing when we move to TableGen.

- Lift ArgList to a base class for InputArgList and DerivedArgList.
- This is not a great decomposition, but it does embed the
translation into the type system, and keep things efficient for
tool chains that don't want to do any translation.
- No intended functionality change.
Eventually I hope to get rid of tool chain specific translation and
have each tool do the right thing, but for now this is the easiest way
to match gcc precisely (which is good for testing).

On a synthetic command line consisting of almost all defined options,
this drops wall time from .00494 to .00336 and user time from .00258
to .00105.
On the same benchmark, clang-driver is about 15% faster than the
primary gcc driver and almost twice as fast as the gcc driver driver.

handled by driver.
- This is not very precise, we use it to drive the "forward-to-gcc"
predicate, when trying to talk to a generic gcc tool.
- Slightly better than what ccc was doing, and should be good
enough. Platforms which want a robust driver should implement a
proper tool chain.

- Use OPT_ prefix for ids.
- Reference groups and aliases by shortend id (on the theory that
this is more readable).
- Rename the special option ids to more protected names.
llvm-svn: 66767
- Add Options.def file, collects option information.
- Actual option instantiation is handled lazily by OptTable to allow
the driver to not need to instantiate all options.
- cast<> support for Option, other minor tweaks.
