Leszek Swirski 2b96e854f5 [compiler] Make accumulator index 0 in liveness bitvectors 
Previously, the accumulator was at the end of liveness bitvectors, which
meant that checking for accumulator liveness required a length lookup.
This CL moves it to the start of the bitvector, with registers starting
at index 1 -- the assumption is that the addition of 1 to the index on
register liveness access can be constant folded away.

As a cleanup, replace all the custom liveness printing code with a
single unified ToString. This places the accumulator at the end of the
printed liveness, to avoid having to change test expectations (also, the
position of the accumulator is now an implementation detail). As a
similar cleanup, change StateValue node building to use the
BytecodeLivenessState interface rather than the underlying bitvector.
These two cleanups allow us to remove the raw bitvector accessor from
liveness entirely.
