The condition was not accurate enough and could interpret some FDEs in .eh_frame or 64-bit DWARF .debug_frame sections as CIEs. Even though such FDEs are unlikely in a normal situation, the wrong interpretation could hide an issue in a buggy generator. Differential Revision: https://reviews.llvm.org/D73886
