variable is moved to the execution engine. The JIT calls the TargetJITInfo
to allocate thread local storage. Currently, only linux/x86 knows how to
allocate thread local global variables.

1. The "JITState" object creates a PassManager with the ModuleProvider that the
jit is created with. If the ModuleProvider is removed and deleted, the
PassManager is invalid.
2. The Global maps in the JIT were not invalidated with a ModuleProvider was
removed. This could lead to a case where the Module would be freed, and a
new Module with Globals at the same addresses could return invalid results.

like the JITMemoryManager to use.

from the union. These are replaced with the single IntVal of type APInt.

ExecutionEngine report errors on creation (like bytecode stuff) and also
help to get rid of exception handling.

This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
The implementation of MutexGuard.h is now based on sys::Mutex which hides
its implementation and makes it unnecessary to have the -NoSupport.h and
-PThreads.h versions of ThreadSupport.
* All places in ExecutionEngine that previously referred to "Mutex" now
refer to sys::Mutex
* All places in ExecutionEngine that previously referred to "MutexLocker"
now refer to MutexGuard (this is frivolous but I believe the technically
correct name for such a class is "Guard" not a "Locker").
These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

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.

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 second exposes what was previously JIT specific state to general clients

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.
