It is middle-end that expands f1 to:

    9: {r92:QI=r88:QI&r90:QI;clobber flags:CC;}
   10: flags:CCZ=cmp(r92:QI,0)
   11: pc={(flags:CCZ==0)?L17:pc}

and f2 to:

    9: flags:CCZ=cmp(r88:QI,0)
   10: pc={(flags:CCZ==0)?L18:pc}

   11: flags:CCZ=cmp(r90:QI,0)
   12: pc={(flags:CCZ==0)?L18:pc}

RTL optimizers are unable to optimize f2 further.
