235b830328 Add a small temporary hack for producing identical eh_frame sections on OS X.
This removes one of the main advantages of moving eh_frame to MC, but
makes the transition a lot easier to debug (run md5).

ed708f9c1f Factor a bit of code to MCStreamer::EmitLabel. Keep track of the last
non private symbol. This will be use for handling

foo:
  .cfi_startproc
  ...

On OS X where we have to create a foo.eh symbol.

bd3327654b Adding support for printing operands symbolically to llvm's public 'C'
disassembler API.  Hooked this up to the ARM target so such tools as Darwin's
otool(1) can now print things like branch targets for example this:
  blx _puts
instead of this:
  blx #-36
And even print the expression encoded in the Mach-O relocation entried for
things like this:
  movt r0, :upper16:((_foo-_bar)+1234)

getEDInfo(), in which case this code would dereference
NULL. EDInst can already handle NULL info, so avoid
the dereference and pass NULL through.

This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.
