ARM: Don't leave alignment checking on after the exception test.

Currently, the exception handling code on ARM turns on alignment checks as an
    easy way to generate an exception for testing purposes. It was leaving it on
    which disabled unaligned accesses for other, unlreated code running later.
    This change adjusts the code so the original value of the alignment bit is
    restored after the test exception.
