Michael Munday 334d410ae3 cmd/compile: fix incorrect block for s390x Select1 op ...

When inserting Select0 and Select1 ops we need to ensure that they
live in the same block as their argument. This is because they need
to be scheduled immediately after their argument for register and
flag allocation to work correctly.

Fixes #38356.
