[PATCH] D58895: [TableGen] Allow lists to be concatenated through '#'

[Javed Absar via Phabricator via llvm-commits]

Currently one can concatenate strings using hash(#), but not lists,  although that would be a natural thing to do. 
This was highlighted by  Nicolai at a FOSDEM talk as well.
This patch allows one to write something like:

  def : A<!listconcat([1,2], [3,4])>;

simply as :

  def : A<[1,2] # [3,4]>;
