c1f3d28d24 Fixes dynamic symbol loading bug on Mac OS X. 
On OS X, when you call dlopen() on a null library, and then call dlsym(),
the most recently loaded symbols are always used, no matter what flags
we seem to pass to dlopen().  The solution is to explicitly find the name
of the running executable, and open that as a library.

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.
