re PR middle-end/168 (Spurious signed/unsigned comparison warning)

PR middle-end/168
* fold-const.c (tree_expr_nonnegative_p):  Handle addition
and multiplication of zero extensions, floating point division,
and integer<->fp, fp<->fp and zero extension conversions.
The built-in ceil and floor functions preserve signedness.

* gcc.dg/20030612-1.c: New test case.
