7ef330478f Implement CopyFromReg, TokenFactor, and fix a bug in CopyToReg. This allows
us to compile stuff like this:

double %test(double %A, double %B, double %C, double %E) {
        %F = mul double %A, %A
        %G = add double %F, %B
        %H = sub double -0.0, %G
        %I = mul double %H, %C
        %J = add double %I, %E
        ret double %J
}

to:

_test:
        fnmadd f0, f1, f1, f2
        fmadd f1, f0, f3, f4
        blr

woot!

0189197608 Before implementing copyfromreg, we'll implement copytoreg correctly.
This gets us this for the previous testcase:

_test:
        lis r2, 0
        ori r3, r2, 65535
        blr

Note that we actually write to r3 (the return reg) correctly now :)

4ccd406317 Now that we have operand info for machine instructions, use it to create
temporary registers for things that define a register.  This allows dag->dag
isel to compile this:

int %test() { ret int 65535 }

into:

_test:
        lis r2, 0
        ori r2, r2, 65535
        blr

Next up, getting CopyFromReg to work, allowing arguments and cross-bb values.

8d30c23d26 Emit this:
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, };

instead of this:

static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, };

For operand information, which does not require dynamic (startup-time)
initialization.

42de581b2f Refactor to use Target.getRegisterClasses consistently, which provides
anonymous regclass definition renaming.

Change the generated code to emit register classes as properly namespace
qualified entities like everything else.

expose the actual class definition as an object, though this isn't quite
usable yet.

d5aa3e26bb Emit real operand info for instructions. This currently works but is bad
in one way: the generated tables require dynamic initialization for the
register classes.  This will be fixed in a future patch.

b822abade7 Give ADJCALLSTACKDOWN/UP the correct operands.
Give a whole bunch of other stuff variable operands, particularly FP.  The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable.  This will have to be fixed before we can dag->dag
the X86 backend.  The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.
