7b9d713f40 Remove uses of getCalleeSavedRegClasses from outside the
backends and removes the virtual declaration. With that out of the way
I should be able to cleanup one backend at a time.

ed310b8bca SelectionDAG shouldn't have a FunctionLoweringInfo member. RegsForValue
shouldn't have a TargetLoweringInfo member. And FunctionLoweringInfo::set
doesn't needs its EnableFastISel argument.

6a3738d96a Add a TargetRegisterInfo::composeSubRegIndices hook with a default
implementation that is correct for most targets. Tablegen will override where
needed.

Add MachineOperand::subst{Virt,Phys}Reg methods that correctly handle existing
subreg indices when sustituting registers.

d76041cf58 Add a -regalloc=default option that chooses a register allocator based on the -O
optimization level.

This only really affects llc for now because both the llvm-gcc and clang front
ends override the default register allocator. I intend to remove that code later.

d13e45d0ec Don't special-case stdout in llvm::WriteBitcodeToFile; just consider
it to be the caller's responsibility to provide a stream in binary
mode. This fixes a layering violation and avoids an outs() call.

83d2cfd6cd Replace the SubRegSet tablegen class with a less error-prone mechanism.
A Register with subregisters must also provide SubRegIndices for adressing the
subregisters. TableGen automatically inherits indices for sub-subregisters to
minimize typing.

CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
index that returns the same register, and ARM NEON Q registers where both D
subregs have ssub_0 and ssub_1 sub-subregs.

It is now required that all subregisters are named by an index, and a future
patch will also require inherited subregisters to be named. This is necessary to
allow composite subregister indices to be reduced to a single index.

3a19b732d8 Replace the tablegen RegisterClass field SubRegClassList with an alist-like data
structure that represents a mapping without any dependencies on SubRegIndex
numbering.

This brings us closer to being able to remove the explicit SubRegIndex
numbering, and it is now possible to specify any mapping without inventing
*_INVALID register classes.
