Cherry Zhang 6bf2eea62a cmd/compile: always use StackMapDontCare as register map index when reg map is not used
When go115ReduceLiveness is true (so we don't emit actual
register maps), use StackMapDontCare consistently for the
register map index, so RegMapValid is always false.

This fixes a compiler crash when doing -live=2 debug print.

Fixes #39251.
