Eliminate mutual recursion in igamma{,c}_impl::Run.
...
Presently, igammac_impl::Run calls igamma_impl::Run, which in turn calls
igammac_impl::Run.
This isn't actually mutual recursion; the calls are guarded such that we never
get into a loop. Nonetheless, it's a stretch for clang to prove this. As a
result, clang emits a recursive call in both igammac_impl::Run and
igamma_impl::Run.
That this is suboptimal code is bad enough, but it's particularly bad when
compiling for CUDA/nvptx. nvptx allows recursion, but only begrudgingly: If
you have recursive calls in a kernel, it's on you to manually specify the
kernel's stack size. Otherwise, ptxas will dump a warning, make a guess, and
who knows if it's right.
This change explicitly eliminates the mutual recursion in igammac_impl::Run and
igamma_impl::Run.
