need to put HeapDump as data section in asm

Currently a treadmill for the whole space will be created, this takes huge amount of time
and even if treadmill space is not used, it needs to be traversed in every gc. Going to
change this tomorrow

make tracing able to trace freelist space (may have degraded
performance, gonna need to tune gc performance later)

cargo test needs ALWAYS run with 1 test thread (RUST_TEST_THREADS=1)

FIXME: GC settings such as heap size, n_gcthreads, should be properly serialized

gonna port tests to this repo
