1139691e3a move all the target's asmprinters into the main target. The piece
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

52a261b3c1 fix a long standing wart: all the ComplexPattern's were being
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

3bf9125933 Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). This
addresses a longstanding deficiency noted in many FIXMEs scattered
across all the targets.

This effectively moves the problem up one level, replacing eleven
FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path
through FastISel where we actually supply a DebugLoc, fixing Radar
7421831.

05ce489871 Merge the SystemZ subreg_even32 SubRegIndex into subreg_32bit. The SubRegIndices
were overspecified when inheriting sub-subregisters, for instance:

R0Q:subreg_even32 = R0Q:subreg_32bit = R0Q:subreg_even:subreg_32bit.

This meant that composeSubRegIndices(subreg_even, subreg_32bit) was ambiguous.

ca561ffcf3 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.

09bc029865 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.

d858e90f03 Use const qualifiers with TargetLowering. This eliminates several
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.
