571e434a34 Turn conditions like x<Y|z==q into multiple blocks.
This compiles Regression/CodeGen/X86/or-branch.ll into:

_foo:
        subl $12, %esp
        call L_bar$stub
        movl 20(%esp), %eax
        movl 16(%esp), %ecx
        cmpl $5, %eax
        jl LBB1_1       #cond_true
LBB1_3: #entry
        testl %ecx, %ecx
        jne LBB1_2      #UnifiedReturnBlock
LBB1_1: #cond_true
        call L_bar$stub
        addl $12, %esp
        ret
LBB1_2: #UnifiedReturnBlock
        addl $12, %esp
        ret

instead of:

_foo:
        subl $12, %esp
        call L_bar$stub
        movl 20(%esp), %eax
        movl 16(%esp), %ecx
        cmpl $4, %eax
        setg %al
        testl %ecx, %ecx
        setne %cl
        testb %cl, %al
        jne LBB1_2      #UnifiedReturnBlock
LBB1_1: #cond_true
        call L_bar$stub
        addl $12, %esp
        ret
LBB1_2: #UnifiedReturnBlock
        addl $12, %esp
        ret

And on ppc to:

        cmpwi cr0, r29, 5
        blt cr0, LBB1_1 ;cond_true
LBB1_3: ;entry
        cmplwi cr0, r30, 0
        bne cr0, LBB1_2 ;UnifiedReturnBlock

instead of:

        cmpwi cr7, r4, 4
        mfcr r2
        addic r4, r3, -1
        subfe r30, r4, r3
        rlwinm r29, r2, 30, 31, 31
        and r2, r29, r30
        cmplwi cr0, r2, 0
        bne cr0, LBB1_2 ;UnifiedReturnBlock
