Merge branch 'verifier-liveness-simplification'
Edward Cree says:
====================
The first patch is a simplification of register liveness tracking by using
a separate parentage chain for each register and stack slot, thus avoiding
the need for logic to handle callee-saved registers when applying read
marks. In the future this idea may be extended to form use-def chains.
The second patch adds information about misc/zero data on the stack to the
state dumps emitted to the log at various points; this information was
found essential in debugging the first patch, and may be useful elsewhere.
