a stop the world mark and sweep has been implemented in f7d1afc but it causes a double free while running sort.sahl

it causes a double free while running sort.sahl

this was fixed. Now the issue is that it isn't concurrent and doesn't gc from coroutines.

implement cheney 4c33473

for the program

fun alloc(i: int) {
    print(i, "\n")
    let a = make([int], 100000000)
    print(len(a), "\n")
}

fun main() {
    let end = 1024*1024
    for i in 0..end {
        alloc(i)
    }
}

old gc: ./sahl ./exe.bin 1.35s user 11.28s system 96% cpu 13.093 total
new gc: ./sahl ./exe.bin 0.86s user 6.08s system 90% cpu 7.696 total
