8c9191c644 The interpreter assumes that the caller of runFunction() must be lli, and 
therefore the function being called must be a main() returning an int.  The
consequences when these assumptions are false are not good, so don't assume
them.

any attempts by LLI to use varargs (possibly left over from the introduction
of IntrinsicLowering??)

8da17489aa Change LLI's internal representation of va_list to a pointer to the next 
argument to be returned by va_arg. This allows va_lists to be passed
between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)

ExecutionContext now keeps Values for each stack frame in a std::map.
printValue() and print() are history.
executeInstruction() is now part of run().

70975eef57 Make CreateArgv part of lli rather than part of ExecutionEngine. 
Switch Interpreter and JIT's "run" methods to take a Function and a vector of
 GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
 into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
 isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
 more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".
