  -----------
  [CodeExtractor] Resolving the Inconsistency of Compiled Binary Files (#86497)

When the compiler enables ALSR by default, binary inconsistency occurs
when the extractCodeRegion function is called. The reason is that the
sequence of traversing ExitBlocks containers of the SmallPtrSet type is
changed due to randomization of BasicBlock pointers.
This fixes https://github.com/llvm/llvm-project/issues/86427
