2605082f0e - Changes how function livein's are handled, they now have a start index of 0. 
- When coalescing a copy MI, if its destination is "dead", propagate the
  property to the source MI's destination if there are no intervening uses.
- Detect dead function live-in's and remove them.

6ad6fdb70b Fixed a long standing spiller bug that's exposed by Thumb: 
The code sequence before the spiller is something like:
                 = tMOVrr
        %reg1117 = tMOVrr
        %reg1078 = tLSLri %reg1117, 2

The it starts spilling:
        %r0 = tRestore <fi#5>, 0
        %r1 = tRestore <fi#7>, 0
        %r1 = tMOVrr %r1<kill>
        tSpill %r1, <fi#5>, 0
        %reg1078 = tLSLri %reg1117, 2

It restores the value while processing the first tMOVrr. At this point, the
spiller remembers fi#5 is available in %r0. Next it processes the second move.
It restores the source before the move and spills the result afterwards. The
move becomes a noop and is deleted. However, a spill has been inserted and that
should invalidate reuse of %r0 for fi#5 and add reuse of %r1 for fi#5.
Therefore, %reg1117 (which is also assigned fi#5) should get %r1, not %r0.

523048ecde Split the addPassesToEmitFile method up into two. This is so that we can 
do some common stuff, then on our own add an object file writer (by calling
a concrete function), and then do some finishing stuff, if need be.

dc0a9a7b4a Two fixes: 
1. Memset takes an i32 for the value to set, not i8.  This was causing GCC to
   ICE all over the place (PR1183).
2. memcpy/memmove were not properly zext/trunc'ing the size in some cases.

19083a4671 switch the VRBaseMap in the scheduler from an std::map to a DenseMap. This

9af2c86bc8 Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate 
their operands with the node itself.  This reduces malloc traffic for operand
