proposed fix to JIT

Consider an ExecutionEngine with two ModuleProviders. In one module, function
foo() is defined, in the other it's declared, and function bar() calls foo().

If you call JIT->getPointerToFunction on bar(), you'll get "Program use
external function 'foo' which could not be resolved!" because it's not even
trying to look in the other Modules for functions of the same name.
