Merge commit eb8f379567e8 from llvm-project (by Florian Hahn):

  [DSE] Remove malloc from EarliestEscapeInfo before removing. (#84157)

  Not removing the malloc from earliest escape info leaves stale entries
  in the cache.

  Fixes llvm/llvm-project#84051.

  PR: llvm/llvm-project#84157

This fixes a crash in clang (usually a bus error, but can also be
another memory error) when compiling the science/siconos port.
