Log: Idea: group in a raw struct all thread-local variables, including a
pointer to errno and the thread ident (for fast access). Then we
basically pass into the jit assembler a pointer to this raw struct.
So the extra cost is a "get the address of this thread-local struct"
before entering jitted code, once.
Benefits include: it would work on dlopened libraries, on OS/X, and
on Windows.
