23d472165f Revert "* numeric.c (ruby_float_step): Avoid error on i386 and amd64." 
r33282 challenged the precision of floating point but:
* Ruby keeps it as platform dependent
* amd64 won't get this issue because compilers for amd64 uses SSE2 to
  calculate floating point numbers instead of x87 FPU.
* this change won't fix the issue under -O
* this commit has no test for the changed behavior
