tcg: Introduce INDEX_op_qemu_st8_i32
Enable this on i386 to restrict the set of input registers for an 8-bit store, as required by the architecture. This removes the last use of scratch registers for user-only mode. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
