fix return for big aggregates
The recent changes in arm and riscv
typclass() set ngp to 1 when a struct
is returned via a caller-provided
buffer.  This interacts bogusly with
selret() that ends up declaring a gp
register live when none is set in
the returning sequence.

The fix is simply to set cty to zero
(all registers dead) in case a caller-
provided buffer is used.
