6e09a5d065 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)

0c1aa958e2 Redirected errors from the AsmParser to the proper 
error stream, in cases where the AsmParser is
being invoked by EDDisassembler.  Before, they
were being sent to errs() because no error handler
was installed in the SourceMgr.

a1467abb18 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.

8c488cb152 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.
