Andrew Lenharth 27f1e26db7 one cannot allocate a global, until one is done initializing the global pointers

Andrew Lenharth 3444cf5128 Like constants, globals on some platforms are GOT relative. This means they have to be allocated 
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.

Andrew Lenharth 940b07c7fa the JIT memory manager will construct a GOT if you want it too. Also, it places the constants in the allocated memory, rather than a malloc area

Reid Spencer 79876f52aa 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.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

Chris Lattner 28edd69eb4 If the interpreter tries to execute an external function, kill it. Of course 
since we are dirty, special case __main.  This should fix the infinite loop
horrible stuff that happens on linux-alpha when configuring llvm-gcc.  It
might also help cygwin, who knows??
