Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.

It only comes into play with a specific order of the LoopPassManager worklist and can cause actual miscompilations, when a SCEV refers to a value that has been replaced with PHI node. SCEVExpander may then insert code into the wrong place, either violating domination or randomly miscompiling stuff. Comes with an extensive test case reduced from the test-suite with bugpoint+SCEVValidator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166787 91177308-0d34-0410-b5e6-96231b3b80d8 Indvars: Don't recursively delete instruction during BB iteration. 2012-10-19T17:53:54Z Benjamin Kramer benny.kra@googlemail.com 2012-10-19T17:53:54Z urn:sha1:7182126b0f3100cfddfbe6939be1a7eaeaf9fd57 This can invalidate the iterators leading to use after frees and crashes.
