c7a012e581 Change RequiresMerge to RequiresUnique. It's a better description of what this
fix is trying to accomplish.

This code could still use some polishing.

a0792de66c - 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.

7f5124829f 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.

b2fc409827 enhance X86TypeInfo to include information about the encoding and
operand kind for immediates.  Use these to define a new BinOpRI

more refactoring before it can make the switcheroo.

e2a268fd03 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.

57d0f2deb0 Update SplitEditor API to reflect the fact that the original live interval is

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.

3a9e7690ba 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.

Make sure it restores local variable N1, which corresponds to the condition operand if it fails to match.

This apparently breaks TCE but since that backend isn't in the tree I don't have a test for it.

3f55c24df9 Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel!
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

548abfcbd6 Implement support for the bizarre 3DNow! encoding (which is unlike anything
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

ec45f60cab Major changes to Cortex-A9 itinerary.
1. Model dual issues as two FUs.
2. Model the pipelines correctly: two symmetric ALUs, the multiplier is a
   dependent pipeline on ALU0.
The changes do not have much impact on codegen right now. But I plan to make
pre-RA scheduler multi-issue aware which should take good advantage of the
changes.

f70007e89e Fix a miscompile in 186.crafty for Thumb2 that was exposed by Evan's
scheduling change in svn 115121.  The CriticalAntiDepBreaker had bad
liveness information.  It was calculating the KillIndices for one scheduling
region in a basic block, rescheduling that region so the KillIndices were
no longer valid, and then using those wrong KillIndices to make decisions
for the next scheduling region.  I've not been able to reduce a small
testcase for this.  Radar 8502534.

8c9aa922a9 This adds a Darwin x86_64 relocation encoding for a subtraction expression
where both symbols are "local", that is non-external symbols, and there is
no "base" for the symbols used in the expression, that is the section has
no non-temporary symbols.  This case looks like this:

% cat local_reloc_A-B.s
	.long 0
LB:	.long 1
	.long LA - LB - 4
	.long 2
LA:	.long 3

which llvm-mc will not encode without this patch, generates a "unsupported
local relocations in difference" error, but the Darwin assembler will
encode with relocation entries like this:

% otool -rv a.out l.out 
a.out:
Relocation information (__TEXT,__text) 2 entries
address  pcrel length extern type    scattered symbolnum/value
00000008 False long   False  SUB     False     1 (__TEXT,__text)
00000008 False long   False  UNSIGND False     1 (__TEXT,__text)

which is very similar to what is encoded when the symbols don't have the
leading 'L' and they are not temporary symbols.  Which llvm-mc and the
Darwin assembler will encoded like this:

Relocation information (__TEXT,__text) 2 entries
address  pcrel length extern type    scattered symbolnum/value
00000008 False long   True   SUB     False     B
00000008 False long   True   UNSIGND False     A

This is the missing relocation encoding needed to allow the Mach-O x86
Dwarf file and line table to be emitted.  So this patch also removes the
TODO from the if() statement in MCMachOStreamer::Finish() that didn't 
call MCDwarfFileTable::Emit() for 64-bit targets.
