  Changed paths:
    M llvm/lib/Transforms/Vectorize/VectorCombine.cpp
    M llvm/test/Transforms/VectorCombine/X86/load-extractelement-scalarization.ll

  Log Message:
  -----------
  [VectorCombine] scalarizeLoadExtract - don't create scalar loads if any extract is waiting to be erased (#129375)

If any extract is waiting to be erased, then bail out as this will distort the cost calculation and possibly lead to infinite loops.

Fixes #129373
