Dan Gohman cd53f64367 Restore LoopUnswitch's block-oriented threshold. LoopUnswitch now checks both ... the estimated code size and the number of blocks when deciding whether to do a non-trivial unswitch. This protects it from some very undesirable worst-case behavior on large numbers of loop-unswitchable conditions, such as in the testcase in PR5259. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84661 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-20 20:06:09 +00:00
