With this, compact dumps omit the trailing (nil) for both regular insns

It also appears removes the trailing (nil) from expr_list.

Bootstrap&regrtest in progress.

OK for trunk if it passes?

This seems OK, with something left to be addressed perhaps in a followup:

+       case JUMP_INSN:
+         return JUMP_LABEL (in_rtx) == NULL_RTX;

Weren't we going to omit JUMP_LABELs in compact mode? If so, we'll need 
a m_compact test here eventually as well.
