  [llvm][CodeGen] Resolve issues when updating live intervals in window scheduler (#101945)

Corrupted live interval information can cause window scheduling to crash
in some cases. By adding the missing MBB's live interval information in the
ModuloScheduleExpander, the information can be correctly analyzed in 
the window scheduler.
