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!

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 :)

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.

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

instructions to all be disjoint.
