3276         pow(x,c)*x as pow(x,c+1) for constant values c.  Optimize x*x
3277         as pow(x,2.0) when the latter will be expanded back into x*x.
3278         (fold <RDIV_EXPR>): Optimize pow(x,c)/x as pow(x,c-1).
3279         * builtins.c (expand_builtin_pow): Ignore flag_errno_math as
3280         pow can never set errno when used with an integer exponent.
3281         Always use expand_powi when exponent is -1, 0, 1 or 2.
3282         (fold_builtin): Don't rewrite pow(x,2.0) as x*x nor pow(x,-2.0)
3283         as 1.0/(x*x).  This avoids unbounded recursion as we now prefer
3284         the pow forms of these expressions.
