if this information were available some other way (say, in the IR).

It can be handy to have all information about options gathered in a single place
to provide an overview of all supported options. This patch allows the following:

def Options : OptionList<[
(switch_option "E", (help "Help string")),
(alias_option "quiet", "q")
...
]>;

Tool-specific option properties (like 'append_cmd') have (obviously) no meaning in
this context, so the only properties that are allowed are 'help' and 'required'.

See usage example in examples/Clang.td.

The following is now allowed:

    (case (not_empty "o"), do_something, ...)

This didn't work previously because "-o" is built-in.

For instance, the following command:

    llvmc2 -E hello.c

now generates a file with the correct suffix (hello.i).

Used like this: (cmd_line "$CALL(MyHook) --option -o $ENV(VARIABLE) $CALL(AnotherHook)")
Also works with case expressions.

Hook declarations are auto-generated, the definitions should be provided by the user
(just drop a .cpp file in the tools/llvmc2 directory).

Hooks should live in the "hooks" namespace and have type std::string hooks::Hook(void).

Besides assigning edge weights, it will also be used by the cmd_line tool property.
