We get this code on ToT for the first LL (the one with the select instruction).
 It looks like the codegen zext issue is gone. Closing the issue.

# BB#0:
        movb    4(%esp), %al
        testb   %al, %al
        jne     .LBB0_1
# BB#2:
        movb    12(%esp), %al
        movzbl  %al, %eax
        movb    8(%esp), %al
        movzbl  %al, %eax
