Description

TableGen: Remove the cast-from-string-to-variable-reference feature

Summary:
Cast-from-string for records isn't going away, but cast-from-string for
variables is a pretty dodgy feature to have, especially when referencing
template arguments. It's doubtful that this ever worked in a reliable
way, and nobody seems to be using it, so let's get rid of it and get
some related cleanups.
