gcc/ChangeLog.gimple-classes:
* tree-ssa-coalesce.c (build_ssa_conflict_graph): Replace
is_gimple_assign with dyn_cast, introducing local "assign_stmt",
using it in place of "stmt" for typesafety.
(create_outofssa_var_map): Within case GIMPLE_ASSIGN introduce
local "assign_stmt", using it in place of "stmt" for typesafety.
