Missing write barriers for MVM_string_find_encoding()

I believe that MVM_file_set_encoding() needs to root oshandle (patch attached) as MVM_string_find_encoding() can allocate and hence can cause a GC run. There are two other uses of MVM_string_find_encoding(). One is: /* At least find_encoding may allocate on first call, so root just * in

Missing write barrier in MVM_sc_get_sc()

I believe that a write barrier is missing in MVM_sc_get_sc(). Patch attached. This was really really messy to figure out. The bug manifests as a SEGV in process_worklist because a pointer to an object is 0x6. Clearly not a pointer. The value 0x6 has come from the scs array of a MVMCompUnit. In tur

Missing root in MVM_hll_set_config()
