3357066875 enhance tblgen to support anonymous defm's, use this to

8137fd6975 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.

not getting marked as mayStore.  This fixes llvm-gcc bootstrap.

5391f55f59 When we find a reaching definition, make sure it is visited from all paths by 
erasing it from the visited set. That ensures we create the right phi defs.

d4b34928be Don't use nextIndex to check for live out of instruction. 
Insert copy after defining instruction.

Fix LiveIntervalMap::extendTo to properly handle live segments starting before
the current basic block.

Make sure the open live range is extended to the inserted copy's use slot.

20b48697cd 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.

5f53528867 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

8b1d76f9e2 Re-apply r115363 and r115366 now that r115525 has removed the un-needed header 
that caused the circular dependencies on Linux.

Built OK for me on OSX and Linux (Ubuntu) with configure/make and CMake. Will
keep an eye on the bots....
