Kalle Raiskila 8b2f70125f Make SPU backend handle insertelement and
store for "half vectors"

Kalle Raiskila 77558b7d13 More SPU v2f32 stuff added: insertelement and shuffle.

Kalle Raiskila 68b3886678 Add preliminary v2f32 support for SPU. Like with v2i32, we just
duplicate the instructions and operate on half vectors. 

Also reorder code in SPUInstrInfo.td for better coherency.

Kalle Raiskila 622f8eb981 Add preliminary v2i32 support for SPU backend. As there are no
such registers in SPU, this support boils down to "emulating" 
them by duplicating instructions on the general purpose registers. 

This adds the most basic operations on v2i32: passing parameters,
addition, subtraction, multiplication and a few others.

Bill Wendling 499f797cdd Rename DBG_LABEL PROLOG_LABEL, because it's only used during prolog emission and
thus is a much more meaningful name.

Jakob Stoklund Olesen 0961c55161 RISC architectures get their memory operand folding for free.
The only folding these load/store architectures can do is converting COPY into a
load or store, and the target independent part of foldMemoryOperand already
knows how to do that.

Dale Johannesen ce97d55ad9 The hasMemory argument is irrelevant to how the argument
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

Kalle Raiskila 0ab5a02579 Mark the SPU 'lr' instruction to never have side effects.
This allows the fast regiser allocator to remove redundant 
register moves.
Update a set of tests that depend on the register allocator
to be linear scan.

Stuart Hastings 0125b6410a 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.

Bill Wendling 95f6ebcb37 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

Dan Gohman 21cea8ac2e 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.

Chris Lattner 1ef9826ff8 "On SPU, variables in the .bss section that are allocated with the .lcomm directive are not aligned on 16 byte boundaries. This causes misaligned loads, as the generated assembly assumes this "default" alignment.
