11421 (fold <RDIV_EXPR>): Optimize pow(x,c)/x as pow(x,c-1).
11422 * builtins.c (expand_builtin_pow): Ignore flag_errno_math as
11423 pow can never set errno when used with an integer exponent.

11426 as 1.0/(x*x). This avoids unbounded recursion as we now prefer
11427 the pow forms of these expressions.
