[Bug rtl-optimization/9085] Unable to find register to spill when optimizing

The testcase from comment #7 doesn't crash since GCC 4.0.0.
The testcase from comment #4 stopped crashing in August or September,
so let's close the bug for good.

None of the testcases fail anymore with GCC: (GNU) 4.5.0 20091001
(experimental) [trunk revision 152374].

The testcase from #7 produces:

foo:
pushl   %ebp
movl%esp, %ebp
pushl   %ebx
movl%eax, %ecx
movl8(%ebp), %eax
movl$3, %edx
movl%edx, %ebx
cltd
idivl   %ebx
movl%edx, (%ecx)
popl%ebx
leave
ret
