[Bug rtl-optimization/24810] [4.1/4.2 Regression] mov + mov + testl generated instead of testb

Simplified testcase seems to work for me on 4.1 branch:
restore_fpu:
        movl    4(%esp), %edx
        movl    boot_cpu_data+12, %eax
        testl   $16777216, %eax
        je      .L2
        jmp     foo
.L2:
        movl    %edx, 4(%esp)
        jmp     bar
"jmp foo" is not elliminated because we don't have pattern for conditional
tailcalls.  Should not be big issue to add the neccesary patterns however.
