Build lli using executionengine library

llvm-svn: 8368

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".

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().

  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.

script).
Removed the use of sys/types.h and sys/stat.h.
Modified FileExists() so that it uses the access() system call to check for
file existance.  This requires less header files and might even be a tad bit
faster.

library code now adds all execute bits that are allowed by the umask value to
the file's current permission bits.

* add prune-eh and inlining passes
* other minor pass reorganizations

Added code to respect the umask value.  Before, files were generated world
readable, which may not be desirable for all installations.

ExecveHandler.c:
* Use "" instead of <> for LLVM include files
* Use raw I/O, we don't need buffering
* Set errno = 0 before using open()
* strlen() doesn't count NULL terminator in its size
* Use memcmp() instead of strcmp()
* Return result of the real execve(), not 0
* Search for path to bytecode file if not absolute/relative path

SysUtils.c:
* Convert all comments to C-style
* Stop using `bool', use `unsigned' instead

SysUtils.h:
* Stop using `bool', use `unsigned' instead
* Updated comment to FindExecutable()

README.txt:
* Describe the goal of LLEE and an application
