    remove SPARC related comment in PPC code generator
    
    Summary:
    PowerPC does not do delay slots and there is also no requirement
    to put extra instructions between FP operations and branches.
    
    Test Plan: None. Comment change only.

 Conditional jumps are always to local labels, so we can use branch
 instructions.  We peek at the arguments to decide what kind of
 comparison to do.

-SPARC: First, we have to ensure that the condition codes are set
-according to the supplied comparison operation.  We generate slightly
-different code for floating point comparisons, because a floating
-point operation cannot directly precede a @BF at .  We assume the worst
-and fill that slot with a @NOP at .

-SPARC: Do not fill the delay slots here; you will confuse the register
-allocator.
