MCJIT support for non-function sections.
Move to a by-section allocation and relocation scheme. This allows
better support for sections which do not contain externally visible
symbols.
Flesh out the relocation address vs. local storage address separation a
bit more as well. Remote process JITs use this to tell the relocation
resolution code where the code will live when it executes.
The startFunctionBody/endFunctionBody interfaces to the JIT and the
memory manager are deprecated. They'll stick around for as long as the
old JIT does, but the MCJIT doesn't use them anymore.

Load multiple object files and link them via RuntimeDyld in llvm-rtdyld.
Relocations between the object modules are properly resolved, as in the
following trivial example:
$ cat t.c
int foo();
int main() {
return foo();
}
$ cat foo.c
int foo() {
return 65;
}
$ clang -c t.c -fno-asynchronous-unwind-tables
$ clang -c foo.c -fno-asynchronous-unwind-tables
$ llvm-rtdyld t.o foo.o ; echo $?
loaded '_main' at: 0x10015c000
65

MCJIT lazy relocation resolution and symbol address re-assignment.
Add handling for tracking the relocations on symbols and resolving them.
Keep track of the relocations even after they are resolved so that if
the RuntimeDyld client moves the object, it can update the address and any
relocations to that object will be updated.
For our trival object file load/run test harness (llvm-rtdyld), this enables
relocations between functions located in the same object module. It should
be trivially extendable to load multiple objects with mutual references.
As a simple example, the following now works (running on x86_64 Darwin 10.6):
$ cat t.c
int bar() {
return 65;
}
int main() {
return bar();
}
$ clang t.c -fno-asynchronous-unwind-tables -o t.o -c
$ otool -vt t.o
t.o:

RuntimeDyld should use the memory manager API.
Start teaching the runtime Dyld interface to use the memory manager API
for allocating space. Rather than mapping directly into the MachO object,
we extract the payload for each object and copy it into a dedicated buffer
allocated via the memory manager. For now, just do Segment64, so this works
on x86_64, but not yet on ARM.

Layer the memory manager between the JIT and the runtime Dyld.
The JITMemory manager references LLVM IR constructs directly, while the
runtime Dyld works at a lower level and can handle objects which may not
originate from LLVM IR. Introduce a new layer for the memory manager to
handle the interface between them. For the MCJIT, this layer will be almost
entirely simply a call-through w/ translation between the IR objects and
symbol names.

Library-ize the dyld components of llvm-rtdyld.
Move the dynamic linking functionality of the llvm-rtdyld program into an

file into memory, use the library to process it, then run the _main()
function, if one is found.

MachO file loader and execution utility.
Add a bone-simple utility to load a MachO object into memory, look for
a function (main) in it, and run that function directly. This will be used
as a test and development platform for MC-JIT work regarding symbol resolution,
dynamic lookup, etc..
