2016-08-11	Add support for fewer preprocessing holes	Andres Notzli
	This commit adds support for the --fewer-preprocessing-holes flag. This flag changes the preprocessing part in proofs in two ways: it (1) removes assertions that are just restating inputs and uses the inputs directly instead and it (2) changes the form of the preprocessed assertions to contain the input that they originate from. The code in this commit is mostly taken from the proofs branch in Guy's fork.
