LiveIntervalMap maps values from a parent LiveInterval to a child interval that
is a strict subset. It will create phi-def values as needed to preserve the
VNInfo SSA form in the child interval.

This leads to an algorithm very similar to the one in SSAUpdaterImpl.h, but with
enough differences that the code can't be reused:

- We don't need to manipulate PHI instructions.
- LiveIntervals have kills.
- We have MachineDominatorTree.
- We can use df_iterator.

order and address size correctly when the value comes from a file address.
Values have "file" addresses when they are globals and the debug information
specifies that they live in the object file at a given address (DWARF will
represent this as a location "DW_OP_addr <addr>"). This causes global pointers
to correctly extract their children on 64 bit programs.

that is. Placeholder ARM implementation simply returns false for now.

The only exception is in parameter passing, where half vectors are
