[PATCH 2/3] Add new keyword externally_initialized to LLVM.

[Michael Gottesman]

I was just thinking about it and I am going to actually split this patch into 2. The first is just adding the actual instance variable and its getters/setters without any actual functionality change. I will add the actual functionality in a later patch with unit tests.
