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it sees is out of date.

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.

Now that we have ghost linkage, we can force resolution of external symbols
...
immediately instead of lazily.
In this program, for example:
int main() {
printf("hello world\n");
printf("hello world\n");
printf("hello world\n");
printf("hello world\n");
}
We used to have to go through compilation callback 4 times (once for each
call to printf), now we don't go to it at all.
Thanks to Misha for noticing this, and for adding the initial ghost linkage
patches.
