Jakob Stoklund Olesen 2dfa8be26a We can split around loops with multiple exits now.

Jakob Stoklund Olesen 89d276aa48 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.

Chris Lattner 907d86db22 fix a bug I introduced in r115669, which ended up with MOV64mr_TC 
not getting marked as mayStore.  This fixes llvm-gcc bootstrap.

did not match. Fixes // rdar: //7933061

John McCall e5dd32da11 Teach PopCleanupBlock to correctly handle the possibility of branching through

Jakob Stoklund Olesen 671bab1c7d 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.

Jakob Stoklund Olesen b0cedd5f96 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.

Douglas Gregor 9b3932c0bc Fix a marvelous chained AST writing bug, where we end up with the 
following amusing sequence:
  - AST writing schedules writing a type X* that it had never seen
  before
  - AST writing starts writing another declaration, ends up
  deserializing X* from a prior AST file. Now we have two type IDs for
  the same type!
  - AST writer tries to write X*. It only has the lower-numbered ID
  from the the prior AST file, so references to the higher-numbered ID
  that was scheduled for writing go off into lalaland.

To fix this, keep the higher-numbered ID so we end up writing the type
twice. Since this issue occurs so rarely, and type records are
generally rather small, I deemed this better than the alternative: to
keep a separate mapping from the higher-numbered IDs to the
lower-numbered IDs, which we would end up having to check whenever we
want to deserialize any type.

Fixes <rdar://problem/8511624>, I think.

Owen Anderson d8d1dcc09a 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.
