Mark and sweep DSW Garbage collector does not work in C RVM

[chouettevan]

The bug

The mark and sweep DSW algorithm does not work, as it does not passes its own benchmarks

Steps to reproduce

clone the repository via git clone https://github.com/udem-dlteam/ribbit
once in ribbit/src, run the benchmarks

HOST=c TEST_TAGS=bench TEST_FEATURES='-f+ c/gc/mark-sweep-dsw' make check

Expected results

The benchmarks run successfully, indicating all tests passed

Actual result

make[1]: Entering directory '/tmp/ribbit/src/host/c'
Running tests with these options:
 - Host: c
 - Ribbit Compiler: ./rsc-gsc.exe
 - Host Compiler: 
 - Tags: bench
 - Options:
  1. (no option)
  2. '-f+ c/gc/mark-sweep-dsw'
Printed numbers are related to the current option being tested from the list above. Tests themselves can be run with different libraries causing numbers to appear multiple times.
