Disable liveness "dead" instruction by default.

The liveness instruction takes up about 10% of the bytecode bloat file.
It is not very useful, it is duplicate information that can be obtained
from the def/user chain.

This change disables the liveness instruction by default.
The caller can track_pseudo_death() if needed.
