test/codegen: merge identical ppc64 and ppc64le tests

Browse source 
Manually consolidate the remaining ppc64/ppc64le test which
are not so trivial to automatically merge.

The remaining ppc64le tests are limited to cases where load/stores are
merged (this only happens on ppc64le) and the race detector (only
supported on ppc64le).
