  -----------
  [BasicBlockUtils] Remove redundant llvm.dbg instructions after blocks to reduce compile time (#89069)

this patch is to fix the compile time for some cases, before this
change, some targets (riscv-64, ve) will spend much more compile time on
this case (https://godbolt.org/z/rrov17cTo). With this change, the
compile time was reduced a lot.
