Chris Lattner	1b35bbe813	change the canonical form of "cond ? -1 : 0" to be ... "sext cond" instead of a select. This simplifies some instcombine code, matches the policy for zext (cond ? 1 : 0 -> zext), and allows us to generate better code for a testcase on ppc. llvm-svn: 94339	2010-01-24 00:09:49 +00:00
