+<li>Implement 'stack slot coloring' to allocate two frame indexes to the same
+ stack offset if their live ranges don't overlap. This can reuse a bunch of
+ analysis machinery from LiveIntervals. Making the stack smaller is good
+ for cache use and very important on targets where loads have limited
+ displacement like ppc, thumb, mips, sparc, etc. This should be done as
+ a pass before prolog epilog insertion.</li>
+<li>Implement 'shrink wrapping', which is the intelligent placement of callee
+ saved register save/restores. Right now PrologEpilogInsertion always saves
+ every (modified) callee save reg in the prolog and restores it in the
+ epilog. However, some paths through a function (e.g. an early exit) may
+ not use all regs. Sinking the save down the CFG avoids useless work on
+ these paths.</li>
<li>Rename ISD::BIT_CONVERT to ISD::BITCAST to match the llvm ir concept</li>
<li>Change the VECTOR_SHUFFLE to be variadic. Right now, a VECTOR_SHUFFLE
takes three operands: two vectors and a shuffle mask. The shuffle mask is
