[Bug target/25199] crashing code output from -mtune=pentium4 but not -mtune=pentiumpro

I think this testcase is too strict in some cases.  With a modified compiler,
we get:
        movb    123(%eax), %dl
        movl    %edx, %esi
...
        movb    120(%eax), %al
        movl    %eax, %esi

Which is correct as far as I can tell, as we only say the lower half of %esi is
defined.
