11411 pow(x,c)*x as pow(x,c+1) for constant values c. Optimize x*x
11412 as pow(x,2.0) when the latter will be expanded back into x*x.
11413 (fold <RDIV_EXPR>): Optimize pow(x,c)/x as pow(x,c-1).
11414 * builtins.c (expand_builtin_pow): Ignore flag_errno_math as
11415 pow can never set errno when used with an integer exponent.

11418 as 1.0/(x*x). This avoids unbounded recursion as we now prefer
11419 the pow forms of these expressions.
