[Bug tree-optimization/22501] New: tramp3d-v4 missed optimizations

[rguenth at gcc dot gnu dot org]

Meta-bug to track (still) missed optimizations in tramp3d-v4 testcase
and so in FreePOOMA library using code.

Full tramp3d-v4 can be fetched from
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/tramp3d-v4.cpp.gz

attached is a reduced testcase (compile-time only), which instantiates
one of the expression kernels representative for the application.  Look
at

;; Function void MultiArgKernel<MultiArg, Function>::run() [with MultiArg = Mult
iArg2<Field<UniformRectilinearMesh<MeshTraits<3, double, UniformRectilinearTag,
CartesianTag, 3> >, double, BrickViewU>, Field<UniformRectilinearMesh<MeshTraits
<3, double, UniformRectilinearTag, CartesianTag, 3> >, double, BrickViewU> >, Fu
nction = EvaluateLocLoop<Adv5::Ekin<3>, 3>] (_ZN14MultiArgKernelI9MultiArg2I5Fie

preferably compile with "-O2 -Dleafify=flatten".
