aba4159be8 Represent va_list in interpreter as a (ec-stack-depth . var-arg-index)
pair, and look up varargs in the execution stack every time, instead of
just pushing iterators (which can be invalidated during callFunction())
around.  (union GenericValue now has a "pair of uints" member, to support
this mechanism.) Fixes Bug 234.

d11cffdfc6 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

The first returns a function pointer or a stub if it's not already generated
  The second exposes what was previously JIT specific state to general clients

8e1bb0bcb2 Make getOperandValue and executeCastOperation methods of Interpreter.
This lets us protect a few more ExecutionEngine methods.

e157a77485 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".

6d7d9f9cd9 Interpreter cleanups:
Get rid of support for DebugMode (make it always off).
Mung some comments.
Get rid of interpreter's PROFILE_STRUCTURE_FIELDS and PerformExitStuff
 which have been disabled forever.
Get rid of -abort-on-exception (make it always on).
Get rid of user interaction stuff (debug mode innards).
Simplify Interpreter's callMainFunction().

cec978e0ed ExecutionEngine.cpp: Move execution engine creation stuff into a new
static method here.
 Remove some extra blank lines.
ExecutionEngine.h: Add its prototype.
lli.cpp: Call it.

Make creation method for each type of EE into a static method of its
own subclass.

Interpreter/Interpreter.cpp: ExecutionEngine::createInterpreter -->
 Interpreter::create
Interpreter/Interpreter.h: Likewise.
JIT/JIT.cpp: ExecutionEngine::createJIT --> VM::create
JIT/VM.h: Likewise.

8bc390da1b The JIT now passes the environment pointer to the main() function when it
starts a program.  This allows the GNU env program to compile and JIT under
LLVM.

because the globals may refer to functions that need to be compiled!
