[clang][NFC] Repair tests for __builtin_convertvector on big-endian
Previously, the macro expansion to be explicit for the test cases had unintentionally forced the tests to always run in little-endian mode. This change restores the tests' endianness switch, and ensures that the tests always run on both a little- and big-endian platform.
