Note that if you pad upward COMPLEX_TYPE (an ABI change), then just the
assign_parm_remove_parallel fix should be enough and you could avoid passing
everything in BLKmode (which pessimizes the code), because the emit_group_store
bug only affects arguments that aren't passed in the first bytes of the
register.
