For Hexagon we want to be able to call functions during debugging, however currently lldb only supports this when there is JIT support. Although emulation using IR interpretation is an alternative, it is currently limited in that it can't make function calls. In this patch we have extended the IR interpreter so that it can execute a function call on the target using register manipulation. To do this we need to handle the Call IR instruction, passing arguments to a new thread plan and collecting any return values to pass back into the IR interpreter. The new thread plan is needed to call an alternative ABI interface of "ABI::PerpareTrivialCall()", allowing more detailed information about arguments and return values.
