[turbofan] Readjust has_slot_use after splintering

[turbofan] Readjust has_slot_use after splintering

has_slot_use is computed early, and we need it to determine if we need
to generate SpillRanges. After splintering, however, the information may
be incorrect - e.g. just the splinter may have slot uses, and not the
original.

Small change that benefits consistency. In addition, it aids a CL where 
we'd avoid unnecessary pre-spilling (this is upcoming).
