fix a tricky bug in the JIT global variable emitter, that was triggered when JITing a variable independently of a function. This lead to sharing memory memory between functions and GVs thus changing the value of a GV could change the code in execution. more details on the ML.

On Darwin ARM, memory needs special handling to do JIT. This patch expands
...
this handling to work properly for modifying stub functions, relocations
back to entry points after JIT compilation, etc..

Rewrite JIT handling of GlobalVariables so they
...
are allocated in the same buffer as the code,
jump tables, etc.
The default JIT memory manager does not handle buffer
overflow well. I didn't introduce this and I'm not
attempting to fix it here, but it is more likely to
be hit now since we're putting more stuff in the
buffer. This affects one test that I know of so far,
MultiSource/Benchmarks/NPB-serial/is.
