*	SI-6968 Simple Tuple patterns aren't irrefutable	Jason Zaugg	2013-01-27	1	-0/+10
	Reverts part of c82ecab. The parser can't assume that a pattern `(a, b)` will match, as results of `.isInstanceOf[Tuple2]` can't be statically known until after the typer. The reopens SI-1336, SI-5589 and SI-4574, in exchange for fixing this regression SI-6968. Keeping all of those fixed will require a better definition of irrefutability, and some acrobatics to ensure safe passage to the ambiguous trees through typechecking.
