The purpose of this option is to silence error messages issued by machine
verifier passes and enable them to run to the end. If this option is not
provided, -verify-machineinstrs complains when it discovers there is a
non-terminator instruction (an instruction that is in a delay slot) after the
first terminator in a basic block.

generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

that it is cheap and efficient to get.

Move a variety of predicates from TargetInstrInfo into 
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around.  Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.

Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.

Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
