* Generate a single BA instead of 6-instruction JUMP if possible
  (this occurs both in the creation and overwriting of the stub code)
* If possible, rewrite the ORIGINAL call to call the generated function
  directly, thus bypassing the stub entirely

Also added some statistics on how often calls are overwritten and how often the
CompilationCallback is invoked.

Don't include InstLoops.h
Don't export factory functions for these passes

Build lli using executionengine library

Build ExecutionEngine as library.

This lets us protect a few more ExecutionEngine methods.

llvm-svn: 8367

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".

 w/ interactive keyboard entry of names.
With that, Support.cpp is history.

llvm-svn: 8360

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.

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().

llvm-svn: 8344

  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.

Add a WHOLE lot of updates clarifications and fixes.  This is not done but getting closer.  I changed the docs to reflect the goal of making unwind an instruction, not an intrinsic.
