don't promote integer division (fix #5409)
work towards making libjulia combilable with a c++ compiler (required for MSVC)
remove redundant typedef and reorder includes in codegen.cpp

Note that extern “C” is not required for julia.h as it is already used
inside the header

fix #5401

type inference was being too greedy by returning `None` for no matching
methods. it's safer to be able to handle methods that might not be
defined yet. we might be able to roll back this change when #265 is
fixed.

Prepare for MCJIT

Adds prepare_call/prepare_global methods to all usages of functions
or global variables. Since MCJIT is multi-module, these will be
needed if the function/global variable is declared in a different
module.
