It looks that the problem with FP compares forcing constant into wrong register
part of this bug is solved. However, register allocator can still be confused
when a variable is initialized to constant value:

grep fldz povray_dump.sse | wc -l
    117
grep fld1 povray_dump.sse | wc -l
    141
grep pxor povray_dump.387 | wc -l
     20

I'll try to provide a small testcase. The testcase (zero.c) attached to this
bugreport is fixed, but anyway I suggest that we reopen this bug.
