37efe67645 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

b003d76cb3 Fix JIT support for static ctors, which was apparently completely broken! 
This allows Prolangs-C++/city and probably a bunch of other stuff to work
well with the new front-end

2fe4bb06c6 Eliminate the dependency of ExecutionEngine on the JIT/Interpreter libraries. 
Now you can build a tool with just the JIT or just the interpreter.

68835dd511 Teach the interpreter to handle global variables that are added to a module after 
interpretation has begun.  The JIT already handles this situation correctly, and
the interpreter can already handle new functions being added.

3db4b62c2f Fix a nasty bug that was causing miscompilation of global variables 
on big endian 32-bit targets in some cases (e.g. PPC).  This fixes several
PPC JIT failures.

ee448630bd For PR540: 
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.

55d86482bd 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.

Also modified some code to not access the GlobalAddress map directly.
