d50f8aa92b Add preliminary frame offsets. 
These are educated guesses at this point. We might need more stack space because
we don't have many free registers available.

517500ba48 Save currently executing lua_State in g->cur_L. 
This is only a good approximation due to deficiencies in the design of
the Lua/C API. It indicates _some_ valid state that is/was executing.
Also reorder L->cframe stores to achieve a synchronously consistent state.
