  [CodeGen] Tweak whitespace in LiveInterval printing

When printing a LiveInterval, tweak the use of single and double spaces
to try to make it clearer that the valnos are associated with the
preceding range or subrange, not the following subrange.

Compare the output before and then after this patch:
