Remove SMT1 parser. (#3228)

This commit removes the SMT1 parser infrastructure and adds the SMT2 translations of the SMT1 regression tests. For now this commit removes regression test regress3/pp-regfile.smt since the SMT2 translation has a file size of 887M (vs. 172K for the SMT1 version). Fixes #2948 and fixes #1313.
