[PATCH 66/89] Make gimple_phi_arg_location_from_edge require a gimple_phi
https://gcc.gnu.org/ml/gcc-patches/2014-04/msg01199.html
from the original 89-patch kit
That earlier patch was approved by Jeff:

* gimple.h (gimple_phi_arg_location_from_edge): Require a
gimple_phi.
* tree-parloops.c (create_parallel_loop): Split up local variable
"stmt", introducing other locals for the various statements created
by this function. Reuse "stmt" within the phi-handling code, and
change to type gimple_phi, since this is the only remaining
"non-phi" user of gimple_phi_arg_location_from_edge.
