  Changed paths:
    M llvm/lib/CodeGen/CodeGenPrepare.cpp
    M llvm/test/Transforms/CodeGenPrepare/X86/statepoint-relocate.ll

  Log Message:
  -----------
  [CodeGenPrepare] Use MapVector to stabilize iteration order

DenseMap iteration order is not guaranteed to be deterministic.

Without the change,
llvm/test/Transforms/CodeGenPrepare/X86/statepoint-relocate.ll would
fail when `combineHashValue` changes (#95970).
