Mikhail Glushenkov e43228958c New feature: OptionList.
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.

// A (first stab at a) replacement for the Clang's ccc script.
// To compile, use this command:
// make TOOLNAME=ccc GRAPH=examples/Clang.td
include "Common.td"
// TOFIX: Add an explicit option list for aliases and things like this.
