Bob Wilson 70aa8d0745 Fix pr6111: Avoid using the LR register for the target address of an indirect 
branch in ARM v4 code, since it gets clobbered by the return address before
it is used.  Instead of adding a new register class containing all the GPRs
except LR, just use the existing tGPR class.

Duncan Sands cbd43f89ac Introduce isOpaqueTy and use it rather than isa<OpaqueType>. Also, move some 
methods to try to have the type predicates be more logically positioned.

Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

Sanjiv Gupta adcee844ea The code section for an ISR has a specific address. 
Currently, whether a function is ISR or not is encoded in the section attribute for that function.

Rafael Espindola af25cf825c Drop support for the InReg attribute on the ppc backend. This was used by 
llvm-gcc but has been replaced with pad argument which don't need any
special backend support.

Bob Wilson a945c64b5a Put repeated empty pattern into the AQI instruction class. 
We could almost use a multiclass for the signed/unsigned instructions, but
there are only 6 of them so I guess it's not worth it.

Evan Cheng 5e73ff2e3a Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

Evan Cheng 3b065cdb64 Teach MachineFrameInfo to track maximum alignment while stack objects are being 
created. This ensures it's updated at all time. It means targets which perform
dynamic stack alignment would know whether it is required and whether frame
pointer register cannot be made available register allocation.
This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test
case.
