From 413ab6655bfe0b1e58d0da6c3f4c3a9833e8a952 Mon Sep 17 00:00:00 2001

Subject: Remove support for interactive (step finish next) instructions.
 Remove printCurrentInstruction, printStackFrame and infoValue  (only used
 interactively) and other unused methods of Interpreter. Fold UserInput.cpp
 containing only callMainFunction() into Interpreter.cpp. Remove unused
 Profile flag.
