The middle-end optimization that builds reversed CRC tables directly changed the dump message. This commit updates the testsuite regexes to match the new message, preventing test failures on targets without a crc_rev optab (e.g., x86 without SSE4.2). This ensures that the testsuite continues to function correctly after the CRC table optimization.
