[Bug target/25305] New: [4.0]: -O2 miscompiled fma3d in SPEC CPU 2K

[hjl at lucon dot org]

Gcc 4.0.3 20051207 miscompiles fma3d in SPEC CPU 2K when -O2 on i686 and
x86-64.
I got
Running Benchmarks
  Running 191.fma3d ref base o2 default
Child returned with invalid return code(0)
*** Miscompare of fma3d.out, see
/export/spec/src/2000/spec/benchspec/CFP2000/191.fma3d/run/00000002/fma3d.out.mis

Gcc 4.1 and 4.2 are OK.
