rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!

have been done anyway).

created here.  Instead they are created in LiveRangeInfo.cpp.  This
simplifies the code here quite a bit.

needs the RegClass list to be passed in.

Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.

 - Make DominatorTree::Node not inherit from std::vector

llvm-svn: 3939

  - Add new methods to LoopInfo: getLoopPreheader, addBasicBlockToLoop.
    These allow extra information to be easily gathered, and loopinfo to be
    updated.

    the end of the function.

llvm-svn: 3934

Converted SimpleStructMutation to take TargetData as a required pass.

Change LowerAllocations pass to 'require' TargetData instead of it being
passed in.
