The "live bytes" count is *really* a "marked black" count - i.e., the count of bytes *known* to be live.

Fix aggravating bug on X64 where assembler code used a value that was off
by a factor of 2^31.

Ensure that sweeping clears live-bytes. Added other missing increments.

Added print statements to trace live-byte modifications, under a flag.

Still a few cases of undercounting left.

(New issue to merge from GC branch to bleeding_edge)

Fix a bug with uninitialized const variables in the optimizing compiler.

We have to check for uninitialized uses before phi-elimination. Otherwise we
may miss such a use and result in using the hole value instead. This
causes a NULL-dereference or assertion failure.

Fix pc to code cache so it can cope with a pointer to the start of the code

Fix a deoptimization bug.

We reset the count of outgoing arguments, used for the index in the
frame's outgoing arguments, for each level of inlining. This could
result in the arguments overlapping, rather than stacking on top of
each other.
