Clemens Hammacher 93526b8543 [wasm][gc] Lower limit to trigger GC 
Since we currently require at least 1 MB of code to be potentially
dead, we will never trigger GC for small modules.
This CL lowers the threshold to 64 kB (plus 10% of committed code
space), which has basically no effect on large modules, but ensures
that we also run GCs on small modules.
