It is already fixed on the tree-ssa:
#APP
        testlabel1: 
#NO_APP
        xorl    %eax, %eax  <--- this is here because z was uninitialized in your example for some cases.
        testl   %edx, %edx
        jle     .L7
        .p2align 4,,15
.L8:
        incl    %eax
        cmpl    %edx, %eax
        jl      .L8
        movl    $4, %eax
.L7:
#APP
        testlabel2: 
#NO_APP
