ELF: Handle empty CIE augmentation string "A zero length string indicates that no augmentation data is present." The FreeBSD/mips toolchain (GCC 4.2.1) generates .debug_frame sections containing CIE records that have an empty augmentation string. Differential Revision: http://reviews.llvm.org/D19928 llvm-svn: 270706

ELF: improve CIE no-augmentation test Add another possible error that may be reported for the same case. The original reproduction case that prompted r270706 produced the error "corrupted CIE" instead of "corrupted or unsupported CIE information". The specific error depends on arbitrary data later in the file so check that neither is emitted in case the input is ever changed. Document the process used to create the input .o and rename the test file to .s, as requested by Rafael. llvm-svn: 270709
