f76053269e Move FCTIWZ handling out of the instruction selectors and into legalization, 
getting them out of the business of making stack slots.

1368721d53 Fix some indentation (first hunks). 
Remove code (last hunk) that miscompiled immediate and's, such as
  and uint %tmp.30, 4294958079

into

 andi. r8, r8, 56319
 andis. r8, r8, 65535

instead of:

 li r9, -9217
 and r8, r8, r9

The first always generates zero.

This fixes espresso.

pulling these copies away from the call.

0bbea95433 Make fsel emission work with both the pattern and dag-dag selectors, by 
giving it a non-instruction opcode.  The dag->dag selector used to not
select the operands of the fsel, because it thought that whole tree was
already selected.

5839bf2b3b Change ConstantPoolSDNode to actually hold the Constant itself instead of 
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.
