Back out change to divide getSpillSize by 8 until I figure out why it breaks x86, which has register sizes in bits.

This bug prevented us from doing most register coallesces.

with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the
same as 8 .byte 0's).  Because we do not know when or when we are not aligned,
just emit bytes like the old V9 asmprinter did.
