Nadav Rotem 94213533f7 Revert 172708. ... The optimization handles esoteric cases but adds a lot of complexity both to the X86 backend and to other backends. This optimization disables an important canonicalization of chains of SEXT nodes and makes SEXT and ZEXT asymmetrical. Disabling the canonicalization of consecutive SEXT nodes into a single node disables other DAG optimizations that assume that there is only one SEXT node. The AVX mask optimizations is one example. Additionally this optimization does not update the cost model. llvm-svn: 172968		2013-01-20 08:35:56 +00:00
