57d0f2deb0 Update SplitEditor API to reflect the fact that the original live interval is
never kept after splitting.

Keeping the original interval made sense when the split region doesn't modify
the register, and the original is spilled. We can get the same effect by
detecting reloaded values when spilling around copies.

3a9e7690ba Use a more efficient lowering of uint64_t --> float that can take advantage of hardware signed integer conversion without
having to do a double cast (uint64_t --> double --> float).  This is based on the algorithm from compiler_rt's __floatundisf
for X86-64.
