[Bug middle-end/19402] New: __builtin_powi? still missing

[pcarlini at suse dot de]

In order to efficiently implement in the c++ run-time library the overloads of
std::pow for integer (*) exponent mandated in 26.5, three additional builtins are
badly needed, for float, double and long double base. For a discussion, see this
thread:

  http://gcc.gnu.org/ml/gcc-patches/2003-07/msg02738.html

See also libstdc++/11706.

(*) But not necessarily constant!
