    Revert 18443d3a74d5: the branch int-test-is-zero is maybe a nice idea · 37894e68890d

    but it doesn't really work.  E.g. when we write "if a & 3:" at app-level
    then the value "a & 3" is anyway passed around as failargs.  So this
    branch makes the CPU compute twice this value, basically.
    
    This is an almost-complete-revert: I'm keeping the new TEST_xx instructions in
    rx86.py because the next time they're needed we'll already have them.
