e53a5af966 I think we got non-machine specific constpool entries covered.

0f282439be Correct way to handle CONSTPOOL_ENTRY instructions.

bc6d876adf Support for constant islands in the ARM JIT. 
Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the 
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

016d34cc4c NeedStub/DoesntNeedStub logic was reversed, leading to not using a stub 
for global relocations that do need them (libc calls, for example).

749c6f6b5e rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

69244300b8 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.

8aa797aa51 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.
