Rewrite the tblgen parser in a recursive descent style, eliminating the bison parser.
This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics. It is also faster, but tblgen probably doesn't
care about performance.
There are a couple of FIXMEs which I will take care of next.
