10062 Attempt to negate a MULT_EXPR or RDIV_EXPR by negating an operand
10063 that's easy to negate, if we don't honor sign-dependent rounding.
10064 (fold <MULT_EXPR>): Optimize -A * B as A * -B if B is easy to
10065 negate, and the symmetric A * -B as -A * B if A is easy to negate.
10066 (fold <RDIV_EXPR>): Likewise, optimize -A/B and C/-D as A/-B and
10067 -C/D if B and C are cheap to negate. Add an explicit rule to
10068 optimize X/-1.0 as -X when we don't care about signaling NaNs.
