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.

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.

Fix a really horrible problem that causes the JIT to miscompile any program
that use 64-bit integers on 32-bit hosts.

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

This is no longer needed. Global variables with undef initializers can be
initialized to anything, including garbage.
