8e5ce11047 refactor memory management code
We now support immortal objects, which the GC will scan for references
but not consider for collection.  On x86_64, we allocate JIT code memory
via mmap, which lets us map memory into the bottom 2GB of the address
space, ensuring that 32-bit relative jumps and calls work.
