863f84648f Made the MC disassembler check before accessing
MCInst operands for ARM.  This allows it to be
more tolerant of malformed MCInsts or incorrect
instruction metadata.

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)

0da9f13faa An MCDisassembler has the option to not implement
getEDInfo(), in which case this code would dereference
NULL. EDInst can already handle NULL info, so avoid
the dereference and pass NULL through.

93f7936435 Again adding a C API to the disassembler for use by such tools as Darwin's
otool(1), this time with the needed fix for case sensitive file systems :) .
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.
