[llvm-commits] Documentation for GlobalValue lifetime requirements around an ExecutionEngine

[Jeffrey Yasskin]

This is an attempt to describe how users have to handle deleting
GlobalValues that they've emitted code for. I'm not sure I have the
requirements right, so please double-check them.

I believe that there's no way to free the memory that
getOrEmitGlobalVariable allocates, but I haven't documented that on
the theory that it's a bug.

I also haven't mentioned the requirement that no thread, including the
current one, is inside a function's machine code when you call
recompileAndRelinkFunction(that_function). I'm not sure if it's
obvious.
