If any def of a machine-sink candidate has local uses, it's obviously not safe to sink it to a successor block. This bug has been hidden because a later check for critical-edge disable these illegal optimizations. This patch should significantly reduce the amount of time spent on checking dominator information for obviously unsafe sinking.

We must complete the DFS, otherwise we might miss needed phi-defs, and

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.

Changed "Error Value::GetValueAsData (...)" to set the data extractor byte
...
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.
