Andrew Trick 5a5a5ebe68 Allow loop unrolling to get known trip counts from ScalarEvolution. ... SCEV unrolling can unroll loops with arbitrary induction variables. It is a prerequisite for -disable-iv-rewrite performance. It is also easily handles loops of arbitrary structure including multiple exits and is generally more robust. This is under a temporary option to avoid affecting default behavior for the next couple of weeks. It is needed so that I can checkin unit tests for updateUnloop. llvm-svn: 137384		2011-08-11 23:36:16 +00:00
