Owen Anderson 6da4d820fa Since the Hello pass is built as a loadable dynamic library, don't try to convert it to new-style registration yet.

Jakob Stoklund Olesen b19bae4e3e Constrain the offset register to a *_NOSP register class when inserting LEA

Jakob Stoklund Olesen b2dd88db6b Properly handle GR32_NOSP in X86RegisterInfo::getMatchingSuperRegClass.

Jakob Stoklund Olesen 18842783cc 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.

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.

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.
