Chris Lattner f4127dd48e 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.

Chris Lattner da4ab67127 reimplement the tblgen lexer with a simple hand-written lexer. This eliminates 
one dependency on flex and gets rid of two ".cvs" files.
