Bill Wendling 10f60fa411 Change RequiresMerge to RequiresUnique. It's a better description of what this 
fix is trying to accomplish.

This code could still use some polishing.

Evan Cheng 49d4c0bd18 - 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.

Bill Wendling cd8fe46d4b 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.

Chris Lattner 6e85be2ecf 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.

Chris Lattner a46073b56b 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).

Bill Wendling 0198ce06fc Provide a fast "get me the target triple from the module" API. This can 
drastically reduce the linking time during LTO.

Chris Lattner 1fc81e90f7 lets go all meta and define new X86 type wrappers that declare the associated 
gunk that goes along with an MVT (e.g. reg class, preferred load operation,
memory operand)

Chris Lattner eadaeaab93 introduce a new BinOpRM class and use it to factor AND*rm. This points out 
that I need a heavier handed approach to get ultimate factorization.

Chris Lattner 9402633637 remove the !nameconcat tblgen feature. It "shorthand" and only used in 4 places 
where !cast is just as short.

Chris Lattner 04c342ea20 replace stuff like: 
let AsmString = !strconcat(
                     !strconcat(!strconcat(opc, "${p}"), !strconcat(".", dt)),
                     !strconcat("\t", asm));

with:

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

:)

!strconcat(!strconcat(!strconcat(!strconcat

register class, and use this to simplify use of BinOpRR.

Jakob Stoklund Olesen 56e2925e6c Remove SplitAnalysis::removeUse. It was only used to make SplitAnalysis 
reusable, but that is no longer relevant since a split will always replace the
original.

Owen Anderson c25b39702f 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.

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.
