tree-outof-ssa.c: Use gassign
gcc/ChangeLog.gimple-classes:
* tree-outof-ssa.c (ssa_is_replaceable_p): Rename param "stmt" to
"gs", replacing is_gimple_assign with a dyn_cast, using it to
reintroduce "stmt" as a gassign * for typesafety. Remove
redundant is_gimple_call (stmt) test, since we've already checked
for a GIMPLE_ASSIGN.
