- 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.

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.

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.
