These are all fixed on the mainline:
The first two examples:
a:
        rolw    $8, %ax
        movzwl  %ax, %eax
        ret
        .size   a, .-a
        .p2align 4,,15
.globl b
        .type   b, @function
b:
        rolw    $8, %ax
        movzwl  %ax, %eax
        ret
For swab16:
swab16:
        movl    4(%esp), %eax
        rolw    $8, %ax
        movzwl  %ax, %eax
        ret
