c44ee01ccc Change RequiresMerge to RequiresUnique. It's a better description of what this 
fix is trying to accomplish.

This code could still use some polishing.

6fbb6dea7c - Add TargetInstrInfo::getOperandLatency() to compute operand latencies. This 
allow target to correctly compute latency for cases where static scheduling
  itineraries isn't sufficient. e.g. variable_ops instructions such as
  ARM::ldm.
  This also allows target without scheduling itineraries to compute operand
  latencies. e.g. X86 can return (approximated) latencies for high latency
  instructions such as division.
- Compute operand latencies for those defined by load multiple instructions,
  e.g. ldm and those used by store multiple instructions, e.g. stm.

9372fed918 If the destination module all ready has a copy of the global coming from the 
source module *and* it must be merged (instead of simply replaced or appended
to), then merge instead of replacing or adding another global.

The ObjC __image_info section was being appended to because of this
failure. This caused a crash because the linker expects the image info section
to be a specific size.

30c9a175a3 enhance X86TypeInfo to include information about the encoding and 
operand kind for immediates.  Use these to define a new BinOpRI
class and switch AND8/16/32ri over to it.  AND64ri32 needs some
more refactoring before it can make the switcheroo.

88ccb4e6b5 sink more intelligence into the ITy base class. Now it knows 
that i8 operations are even and i16,i32,i64 operations have a
low opcode bit set (they are odd).

0bc415a491 Generalize tblgen's dag parsing logic to handle arbitrary expressions 
as the operator of the dag.  Specifically, this allows parsing things
like (F.x 4) in addition to just (a 4).

Unfortunately, this runs afoul of an idiom being used by llvmc.  It
is using dags like (foo [1,2,3]) to represent a list of stuff being
passed into foo.  With this change, this is parsed as a [1,2,3] 
subscript on foo instead of being the first argument to the dag.
Cope with this in the short term by requiring a "-llvmc-temp-hack"
argument to tblgen to get the old parsing behavior.

let AsmString = !strconcat(
                     !strconcat(!strconcat(opc, "${p}"), !strconcat(".", dt)),
                     !strconcat("\t", asm));

with:

  let AsmString = !strconcat(opc, "${p}", ".", dt, "\t", asm);

38e84dd7ea Another step towards getting rid of static ctors for pass registration: have INITIALIZE_PASS AND INITIALIZE_AG_PASS 
expand to an initializeMyPass() function (in additional to the extant static ctors).  Eventually, these will be called
from a big InitializeAllPasses() function, and the PassInfo's they create (which would be leaked if this code were used
at the moment) will be handed off to a PassRegistry for ownership.

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.
