635127a8c6 Constrain the offset register to a *_NOSP register class when inserting LEA 
instructions.

This unbreaks the machine code verifier and fixes PR8317.

82df5096ea add a common SDPatternOperator base class to SDNode and PatFrag for 
stuff that wants to take one or the other.  These can both be used
as the operation of a dag in a pattern match.

bf4699c561 Add MachineRegisterInfo::constrainRegClass and use it in MachineCSE. 
This function is intended to be used when inserting a machine instruction that
trivially restricts the legal registers, like LEA requiring a GR32_NOSP
argument.

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.

46f55527d8 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.
