    testsuite: require cortex-a53 in reg_equal_test.c test
    
    The original purpose of the test is to verify that, when the backend
    emits a mov-pair sequence, the sequence carries a REG_EQUAL note for the
    final constant value.  Make that precondition explicit instead of
    depending on target-specific tuning behavior, by forcing the test to
    a CPU with the required properties.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/arm/reg_equal_test.c: Add require effective target
            cortex-a53 for test.

    (cherry picked from commit 8d16b075796e77e2160bee01678b35fc0568dc36)
