Use MDNodes to encode debug info in llvm IR.

Let Darwin linker auto-synthesize stubs and lazy-pointers. This deletes a bunch of nasty code in ARM asm printer.

Some other minor win64 fixes as well.

Patch by Michael Beck!

This implements the maximum spanning tree algorithm on CFGs according to
weights given by the ProfileEstimator. This is then used to implement Optimal
Edge Profiling.

Also, all one of the file level flags are implemented.

 - I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences.

Add MO flags to simplify the printing of relocations.
Remove the support for printing large code model relocs (which
aren't supported anyway).

No idea whether this is profitable or not.

 - No relocations yet, of course.

 - Note, this is a gigantic hack, with the sole purpose of unblocking further
   work on the assembler (its also possible to test the mathcer more completely
   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc
   (although some encodings are probably incorrect). This is a testament to the 
   beauty of X86's MachineInstr, no doubt! ;)
