instructions (instructions that are not NOP).

Akira Hatanaka 8b3666af1b Remove unnecessary check. isDelayFiller(MBB, I) will evaluate to true before 
I->getDesc().hasDelaySlot() does.

Akira Hatanaka 7d398636a2 Add comments and move assignment statement. If sawStore is true, sawLoad does 
not have to be set.

Akira Hatanaka f2619ee3ff Fill delay slot with useful instructions. Modified from Sparc's version of delay 
slot filler.

Patch by Reed Kotler at Mips Technologies.

Evan Cheng 6cc775f905 - Rename TargetInstrDesc, TargetOperandInfo to MCInstrDesc and MCOperandInfo and 
sink them into MC layer.
- Added MCInstrInfo, which captures the tablegen generated static data. Chang
TargetInstrInfo so it's based off MCInstrInfo.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Chris Lattner 03ad885039 rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

Chris Lattner a98c679de0 Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects 
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.
