commit 50bb06ce3b990c2e282b7245b5fdcea119f6385f
Author: Philip Herron <philip.herron@embecosm.com>
Date:   Wed Aug 10 10:48:15 2022 +0100

    Seperate 64 and 32 bit testing combos into seperate jobs
    
    Change the CI requirements to have seperate jobs for 64 and 32 bit testing.
    It also runs both combinations on the gcc4.8 build job. Bors only requires
    the normal build check 64bit job to pass to minimize impact.
