This revision adds the 'true' and 'false' literals to TableGen, which represent boolean values.

This is primarily syntactic sugar aimed at improving the readability of TableGen files. Once parsed, these literals are converted to 1 and 0. Note that they can be used in bit sequences, too.

The documentation was updated. A test was added and a couple of other tests updated due to an improved error message.
