  Log Message:
  -----------
  [ELF] --icf: don't fold a section without relocation and a section with relocations for SHT_CREL

Similar to commit 686cff17cc310884e48ae963bf7507f96950cc90 for SHT_REL (#57693).
CREL hasn't been tested with ICF before.

And avoid a pitfall that eqClass[0] might interfere with ICF.

(cherry picked from commit e82f0838ae88ad69515ebec234765e3e2607bebf)
