Remove floating point killer pass. This is now implemented in the
...
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

Finally, _actually delete the machine code_ for a function, after it has
...
been emitted. Also, since the FPK pass is causing memory access violations,
disable it.

a pointer. This evades a warning emitted by GCC when we cast from
unsigned int (32 bit) to void * (64 bit) on SparcV9.
