 Combiner-AA improvements, why not on by default?

 New LSR with full strength reduction mode
 The most awesome sext / zext optimization pass. ?
-
+Better code size analysis in loop unswitch, inliner code split out to a new 
+  CodeMetrics class for reuse.
 The ARM backend now has good support for ARMv4 backend (tested on StrongARM
   hardware), previously only supported ARMv4T and newer.
-
+Half-float support in APFloat
+Indirect branch + address of label (blog post), particularly useful for interpreters.
+Many changes to the pass ordering for improved optimization effectiveness.  
+
+Opt now works conservatively if no target data is set (is this fully working?)
+Target data now has notion of 'native' integer data types which optimizations can use.
+ARM backend generates instructions in unified assembly syntax.
+New Analysis/InstructionSimplify.h interface for simplifying instructions that don't exist.
+Jump threading is now much more aggressive at simplifying correlated
+   conditionals and threading blocks with otherwise complex logic. CondProp pass
+   removed (functionality merged into jump threading).
+X86 and XCore supports returning arbitrary return values, returning too many values is
+   supported by returning through a hidden pointer.
+verbose-asm now produces information about spill slots and loop nests
 
 
 Defaults to RTTI off, packagers should build with make REQUIRE_RTTI=1.
-CondProp pass removed (functionality merged into jump threading).
 AndersAA got removed (from 2.7 or mainline?)
 PredSimplify, LoopVR, GVNPRE got removed.
 LLVM command line tools now overwrite their output, before they would only do this with -f.
