Initial set of .td file changes necessary to get scalar fp in xmm registers

working. The instruction selector changes will hopefully be coming later
this week once they are debugged. This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87. As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier. This leads to significantly
better codegen in several cases.

When compiled with GCC 4.0, a latent bug was exposed where both SparcV9
...
and the target independant register allocator were both using a class named
'LiveRange'. This lead to the target independant code calling code in the
SparcV9 backend, which crashed. Fixed by renaming SparcV9's LiveRange to
V9LiveRange.

Handle some more real world cases of rlwimi. These don't come up that

regularly in "normal" code, but for things like software graphics, they
make a big difference.
For the following code:
unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
unsigned tmpA,tmpB,mixed;
tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}
We now generate:
_Trans16Bit:
.LBB_Trans16Bit_0: ; entry
andi. r2, r4, 31775
rlwimi r2, r4, 15, 7, 11

Use target-specific nodes for calls. This allows the fastcc code to not have
...
to do ugly hackery to avoid emitting code like this:
call foo
mov vreg, EAX
adjcallstackup ...
If foo is a fastcc call and if vreg gets spilled, we might end up with this:
call foo
mov [ESP+offset], EAX ;; Offset doesn't consider the 12!
sub ESP, 12
Which is bad. The previous hacky code to deal with this was A) gross B) not
good enough. In particular, it could miss cases and emit the bad code above.
Now we always emit this:
call foo
adjcallstackup ...
mov vreg, EAX
directly.
This makes fastcc with callees poping the stack work much better. Next
stop (finally!) really is tail calls.
