Jim Grosbach 3ed03f18d1 Tidy up a bit now that we're using the MemoryManager interface.

Jim Grosbach 18b81c52bb Refactor MCJIT 32-bit section loading.
Teach 32-bit section loading to use the Memory Manager interface, just like
the 64-bit loading does. Tidy up a few other things here and there.

Jim Grosbach 23de2437bd 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.

Jim Grosbach 2dcef0505f 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.

Jim Grosbach f016b0a359 Library-ize the dyld components of llvm-rtdyld.
Move the dynamic linking functionality of the llvm-rtdyld program into an
ExecutionEngine support library. Update llvm-rtdyld to just load an object
file into memory, use the library to process it, then run the _main()
function, if one is found.

Jim Grosbach 486e57f694 Add llvm-rtdyld support for loading 32-bit code.
Factor out the 64-bit specific bits into a helper function and add an
equivalent that loads the 32-bit sections. This allows using llvm-rtdyld on ARM.

Jim Grosbach 0072cdbc50 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..
