[PATCH v4 29/36] target/s390x: Copy wout_x1 to wout_x1_P


From: Richard Henderson
Subject: [PATCH v4 29/36] target/s390x: Copy wout_x1 to wout_x1_P
Date: Sat, 7 Jan 2023 18:37:12 -0800

Make a copy of wout_x1 before modifying it, as wout_x1_P
emphasizing that it operates on the out/out2 pair.  The insns
that use x1_P are data movement that will not change to Int128.
